== What is Time domain signal ==
The time domain signal window shows the 2048 samples captured of the IF radar signal on the last measurementeach captured frame.
Y axis represents the signal voltage.
X axis is represents the time in microseconds or also it can be the sample number.
In the picture below we can see a measurement using the default a -T 600 modulation over a wall about 3m 2m distance from radar is shown. As we will see later, modulation parameters can be changed, in this case we have selected a modulation ramp with a duration of 600us. Considering that the time to get 2048 samples with the default modulation is 3,471ms and we can see about 16 20 periods of the sinusoidal signal this means that the dominant sinus shown below is about 45,609KHz 760KHz frequency. The frequency of the IF radar signal is proportional to the distance from the radar to the target (in this case the wall).
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [[Image:WEBWAVE 2m -WAVE3mBT 600 NEWs.jpg]]<br>
<br>
We will learn later can know at any moment the exactly parameters the radar is working on the below lines of the graphs:<br>  <br>  [[Image:WAVE LEGEND NEWs.jpg]]  In this case we can identify on next chapters how the last line the modulation parameters used to know make the measurement: The radar start frequency is 24 GHz with a bandwith of 250MHz and a modulation ramp of 604us. Note that although we have selected 600us the radar has a limitation in discrete values and has been configured with the closest value, in this case 604us. We can see also the sampling rate (590ksps) and the modulation parameter Hzpm (herz per meter) that indicates the IF frequency relation with distance.  The "MEASURES" line indicates a refresh time of 333ms (this means that in this moment we visualise about 3 frames per second) and the points per each transfer are 2048.  The "DISPLAY" line offers the possibility to get 2048 change the units of the x-axis. We can select time or samples. The "CONTROLS" line let us to activate or de-activate the tooltip (check with the mouse the exactly coordinates of an specific point on the graph) and also generate a data list by deactivating the "Enable refresh" option.<br>  <br>
=== What's This? ===
Why I am getting this weird signal? It has no sense, my Radar does not works!
 
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [[Image:WAVE CHAOS NEWs.jpg]]
 
<br>
No. Please, be patient, this is completely normal, your radar works well. If you are getting a signal like this or even still more strange this means that you are detecting different objects. This signal is the result of adding different sinus waves with different frequencies resulting on an apparently noisy signal but in fact is a typical IF radar signal on a multitarget environment. Our main objective now is try to get a clear signal from a single target to start learning with the radar, so please try to slightly change the radar orientation in order to get only a single reflection, or if you are on a small room, try to go to a better scenario, on a wider room with few objects or simply outside close to a wall.<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp; [[Image:WEB-WAVEwhatsthis.jpg]] &nbsp;&nbsp;&nbsp; <br>
== Basic FMCW Radar Theory ==
<br>
In our example, as the default modulation has the next paramenters:
BW=250MHz
T=1,311ms 604us
V=3*108m/s<br>the resulting hzpm is 1271Hz2759Hz/m
So, if the measured IF radar signal frequency is 45,609KHz 760KHz it means the target is at a distance of 32,6m 08m from the radar.
Considering the radar has an offset of about 0,35m (this is due to the microwave signal has this electrical lenght internally on the equipment before to reach the antenna) the real distance results in 31,25m73m<br>
== What is Frequency domain signal ==
The frequency domain signal is the result of applying the FFT to one ramp modulation interval of the 2048 sampled IF radar signal captured samples.<br>
The You can see the spectrum of the radar application takes IF signal in real time thanks to the samples power of one single ramp and completes the rest with zeros (padding) completing 2048 samplesOMAP processor, and it performs the FFT over these 2048 samples, resulting by clicking on the spectrum of the signal with 2048 points resolution. "F(jw)" icon:
<br> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [[Image:WEB HOME PAGE F(jw) NEW.jpg]]  The radar application takes the samples of a single ramp and, if needed, it completes the rest with zeros (padding), thus completing the 2048 samples. Then it performs the FFT over these 2048 samples, resulting on the spectrum of the signal with 2048 points resolution:
<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [[Image:WEBFFT 2m -FFT3mBT 600 NEWs.jpg]]<br>
<br>
Following our example, the above picture shows the FFT of the measurement. Y axis represents signal strenght and X axis represents the FFT sample. Note that only the 300 500 first samples are shown.
We can see a dominant peak centered about sample number 16. This peak should correspond to the measured dominant sinus of 45,609KHz 760KHz on time domain graphic.<br>
The sampling rate used by the equipment with the default modulation is 590Ksps. This means that each sample of the FFT represents 590000/2047=288,2Hz.
If the peak is centered about sample 16 20 it means the frequency represented is 1620*288,2Hz=45,611KHz764KHz, thus corresponding with accuracy with the calculations made on time domain.
We can see other small peaks at about samples 40 and 50. These peaks are due to other reflections on the room at a longer distance. So here an example of the possibilities of the radar to detect several targets at different distances. But by the moment is better if we pay our attention on a single target scenario to keep learning about the radar signal and later we will be able to analyse more complex scenarios.
<br>
= Compare Measurements =
Now you can move the radar and make measurements over the wall at three two different distances. For example, make a measurement with the radar at 2m distance and another measurement with the radar at 5m distance. You should get similar results as the following for 2m, 3m and 5m in order:<br>
&nbsp;<br> [[Image:COMPARING_RADAR_MEASUREMENTS.jpg]]
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [[Image:WEB-WAVE2ms2.jpg]]
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [[Image:WEB-WAVE3mB.jpg]]
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [[Image:WEB-WAVE5mBIt can be clearly shown how the IF radar signal increases frequency when the target gets more and more distance from the equipment.jpg]] Look at the increment in periods (frequency) in the time domain signal, and the FFT peak has moved towards higher frequencies.<br>
<br>
It can be clearly shown how the IF radar signal increases frequency when the target gets more and more distance from the equipment. = What is "Speed/Range" section =
<br> In the right column of the Home Page we can see three different applications of the radar. Only "Speed/Range" demo application is activated, please if you are interested in the others contact with us at mailto:radar@iseebcn.com
<br> Now you can also make use of "Speed/Range" web application demo feature.This application demo measures the speed and range of a single object and can be used for example for traffic management systems.
= What is Click on "Real TimeSpeed/Range" section =icon:
Now you can also make use of this web application demo feature&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [[Image:WEB HOME PAGE speed-range NEW. jpg]]
If you click on "Real Time" icon you will be able to continuously monitor the speed and the distance In case of a single target as much time as wall at 6.1m distance you need. should get something like this:<br>
In case of a wall at 4.9m distance you should get something like this:<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [[Image:WEBSPEED-REALTIMERANGE 6m -5mT 1600 NEWs.jpg]]<br>
Note that in this case you get always the same position (4.9meters) and speed (0Km/h) as our target is a no moving object (wall). <br>
Note that in this case you get always the same position (6.1meters) and speed (0Km/h) as our target is a no moving object (wall).  You have a real time bar indicating the target range (orangegreen) and another real time bar indicating the speed (blue).
There is also a graphic where:
X axis is time
Each point of the graph is one combined position-speed measurement, position in orange green color and speed in blue color.
You can see on next chapter examples of real traffic measurements where you can see how the radar track the vehicles measuring its position and distance.
= What is "TechnicalParameters" section =
This is the most interesting feature of the web application demo. By clicking on "TechnicalParameters" icon you will get access to the heart of the radar. You will be able to make measurements with the modulation you want, by simply&nbsp; prompting the parameters on the rectangles.<br> :
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; [[Image:WEB-TECHNICALHOME PAGE parameters NEW.jpg]]  <br>  You will be able to make measurements with the modulation you want, by simply&nbsp; prompting the parameters on the rectangles.<br>  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; [[Image:PARAMETERS NEWs.jpg]]<br>
There are three sections:
=== SECTION-1: RADAR CALIBRATION CURRENT PARAMETERS<br> === Clicking on "Check" icon you will get the last modulation parameters modified.<br>  <br>  === SECTION-2: UPDATE PARAMETERS === You can type in this section the modulation parameters you want to change. For example, if you want to reduce the modulation bandwith to 150MHz and increase the sweep time to 5000us you should type: -W 150 -T 5000 and then click on "UPDATE" icon. Then, from now the radar is configured with these new parameters and all measurements will be done in these new conditions until a new parameter change is performed.  <br>  === SECTION-3: LIST FILES<br> === You can check at any moment the data files you have saved on the radar by clicking on any of the three buttons, depending if you only want to check sample files, or FFT files or all the files.For example, if you click on "Only WAVE Files" button it will appear a list of files of the captured data similar to this:<br>  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [[Image:FILES NEW.jpg]]<br>  <br>  <br> You have the possibility to:  -Browse: represent a time domain graphic of its contents.  -Figure. the same as before  -Download: Check the data contained on this file, this is a column with the 2048 samples of the IF radar signal. You can select and copy to a text file for post-processing
This feature is for advanced measurements and we do not recommend -Remove: click here if you want to use on remove this chapter. It will be explained later. file
<br>
SECTION-2When clicking at "Download" option you will get a column with all the 2048 captured samples. This is useful to get measurements data and copy to another processing software application like excel or matlab: RADAR MEASUREMENT <br>
This feature is interesting if you want to use the web application demo as a console where you can configure the radar with different modulations and get the results prompted on the screen or saved on a text file[[Image:WEB-FILES-contents2. jpg]]<br>
You can see that the default parameters are<br>  <br>  === SECTION-4: -F 3C0000 -s 50 -i 512 -S 80 -m 3. RADAR MEASUREMENT<br> === <br> This feature is interesting if you want to use the same default modulation used on the Home Menu icons f(t) and F(jw). Now here web application demo as a console where you can remove these parameters configure the radar with different modulations and put what you wantget the results prompted on the screen or saved on a text file.
For example, put in this section the next commands:
and click on "RUN" button
 
<br>
-T 800 means you want a modulation with 0,8ms sweep time
-m 20 means that you want to make 20 consecutive measurements
 
<br>
You can check a complete explanation of each parameter on the user manual of the radar.
The result obtained over a wall at 4.8m distance is like this:
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [[Image:TECHNICAL-wall-4.8m8m2.jpg]] <br>
<br>
Finally, the last column indicates the name of the captured file. IMPORTANT: This file will be generated and stored ONLY if you add the parameter -w
-w means that you want to write all the measurements on a file (there will be generated 20 files, one for each measurement, and each one with 2048 samples) <br>  <br>  === SECTION-5: PARAMETERS === This section is a list of all the parameters that can be used to configure the radar.  {value} means that the parameter has to be followed by a value. [ ] contains the default value.  Check [http://www.isee.biz/component/zoo/item/igep-radar-lambda-hardware-reference-manual IGEP RADAR LAMBDA user manual] or [http://www.isee.biz/component/zoo/item/igep-radar-lambda-hardware-reference-manual IGEP RADAR EPSILON user manual] iif you want to know more about the meanning of the file names. = Managing Files<br> = IGEP RADAR LAMBDA and IGEP RADAR EPSILON offer several ways to manage its files. Here we present some of the most interesting but of course you can use others if you prefer:  <br>  == Files with included demo web == We have already seen on previous section how to manage files with web demo application. You click on "Parameters" icon, then you go to "List Files" section and select the file you want.<br>  By clicking on "Download" option you obtain a list of 2048 values that represent the captured samples if you have selected "Wave" files or the FFT values if you have selected "FFT" files.<br>  You can use the mouse and select all or only one part of the data, copy and paste to a text file for later processing with other applications like excel, labview or matlab.  You can also click on "Edit" section of your browser, then click on "Select All", then click on "Copy" and then paste all the data into a text file.  And there is a third option, by clicking on "File" section of your browser and simply "Save as" text file.   == Files using Samba Network Shared Folder == You can manage the files of your IGEP Radar solution by connecting to a Network Shared Folder of the Radar in your computer via Samba. The network share is called "RADAR" and the shared resource is called "data". Here are some instructions to connect to it: For example, if you are using Windows, open a new file browser window and type: \\radar in the direction bar: [[Image:Radar samba windows.png|center]]  Finally, select the data folder to access the radar data files. And if you are usign Linux, you can mount the Samba share by browsing the Network Shares with the File Manager: [[Image:Radar samba linux.png|center]]  == Files using WinSCP == Another option to manage files by using the [http://winscp.net/eng/index.php WinSCP] free application.<br>  Once installed you only have to connect to the radar and start managing files as with other explorer applications.You can edit, copy, paste, remove and rename files on an easy way.  <br>  <br>  == Files using Linux == You have a third option to manage radar files.<br>  You can also connect to your IGEP Radar Solution via SSH to the system console and use standard Linux commands. Here are some useful links and basic commands:  [http://www.linuxforums.org/forum/forum.php Linux Forum]  [http://www.linuxquestions.org/ Linux Questions]  [http://www.tuxfiles.org/linuxhelp/fileman.html Manage Files in Linux]<br>  '''cd'''&nbsp; to change directory path  '''rm'''&nbsp; to delete a file  '''mkdir'''&nbsp; to make a directory  '''cp'''&nbsp; to copy a file
<br>
SECTION-3=== Capture measurement results === Linux is an interesting environment to generate files of radar measurement results. Here we present some examples on how to save measurement results into a file: RADAR CONTINUOUS MODE  &nbsp;
This section is used to get the same graphics as the obtained on the Home Menu icons f(t) and F(jw), but in this case we can remove the default modulation and put the parameters we want. By checking on TIME or FFT we will obtain the time domain or the frequency domain graphic.<br> ==== Example 1: ====
For example, remove You want to capture 5 consecutive measurement results into a file named measure5.txt. then you must prompt the default modulation and putnext command line:
./radar -T 1000 m 5 &gt;measure5.txt<br>NOTE: Remember you must be in the "radar" directory and you must execute "radar_init.sh" at least once before start doing measurements.
This will program the modulator with a 1ms modulation ramp. If you click the "RUN" button you will see in pseudo-real time the time domain or the frequency domain graph of the IF radar signal. <br>
= What is "Files" section =Now you can check the measurement results in the generated measure5.txt file, and you will see something like this:

The next picture is a graph obtained making use of "Real TimeSpeed/Range" feature of the web radar application demo. It was obtained placing the radar on on a tripod close to a road on one side, with the radar oriented on a 15 to 30 meters field of view, as shown on below pictures:  [[Image:SPEED-RANGE-C NEWs.jpg]]  It can be clearly seen how radar tracks the target from 13 to 31 meters (linear green points) and how the target is slightly increasing the speed from 54 to 56Kmph.<br>  In the next picture several targets were detected in different time intervals:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Set up used to make the measurements: Radar fixed on a tripod oriented on one side of the road<br>
<br>
The modulation used to make this measurement was:
-T 5000 -l 80 -r<br>  -r&nbsp; ===&gt; it means we want to make consecutive measurements without limitation<br>  -T 5000 ===&gt; we apply a modulation sweep time of 5ms  -l 80 ===&gt; this is the signal level threshold. If the radar detects a signal over this level it will start making measurements until level returns below this threshold, when the radar will stop taking measurements. Each time it detects a signal over this threshold it will present the results. This parameter is very important in order we obtain only desired signals and not noise that would provide unreadable results.  There is not a fixed rule to obtain this threshold value because it depends on a lot of things, mainly of the modulation applied, the environment and the type of measurement, so the best is to make first some trials to adjust this value on an empirical way until the system works properly in your specific application and you obtain readable results.  You have to put this modulation parameters on the command block of the "Real Time" window and press enter.  <br>  '''<u>If you want to make faster measurements there is a second procedure to follow:</u>'''  open the console and execute these instructions:  ./radar_init.sh  ./radar -r -T 5000 -x 3000 -X 90000 75000 -l 80 -H
<br>
radar.init ===&gt; it is necessary only -T 5000 sets the first modulation sweep time in order to initialise parameters of the radar application demo.  -H ===&gt; this parameter opens a socket in order the web server application can go faster reading results of the measurements. 5ms
-x 3000 ===&gt; this is a limitation on the processing range, in order to avoid false measurements due to close objects, closer than 3m.<br>
-X 90000 75000 ===&gt; the same as before but applying for far objects, beyond 90m75m.
<br> -l 80 ===&gt; this is the signal level threshold. If the radar detects a signal over this level it will start making measurements until level returns below this threshold, when the radar will stop taking measurements. Each time it detects a signal over this threshold it will present the results. This parameter is very important in order we obtain only desired signals and not noise that would provide unreadable results.
ThenThere is not a fixed rule to obtain this threshold value because it depends on a lot of things, mainly of the modulation applied, you must open the socket environment and the type of measurement, so the best is to make first some trials to adjust this value on an empirical way until the web server by prompting this address:<br> system works properly in your specific application and you obtain readable results.
http://192You have to put this modulation parameters on the command block of the "Parameters" window and press enter.168.2.232:8000/realtime.html
<br>
 
Now the radar is ready to make faster measurements and get more than one measurement per vehicle.
<br>
Note that <u>'''an important thing to consider in this kind of measurements is the correct orientation of the radar'''</u>. This is something you also must empirically optimise for your specific application.

IGEP&nbsp;RADAR LAMBDA and IGEP RADAR EPSILON can be used on this kind of application when pressure and temperature conditions are not extreme and no chemical corrosive material is surrounding the equipment. You only have to install the radar at the top of the tank with the antenna facing the material surface contained on the tank and start measuring range.
In case of extreme environmental conditions it would be needed to develop special antenna that can support high pressures and temperatures. ISEE engineering team is able to develop such kind of devices, please contact with&nbsp; [mailto:radar@iseebcn.com radar support] if you want we study your personal case.

'''The following applications require the development of an specific hardware and/or software to convert IGEP RADAR LAMBDA into a product. Please do not hesitate to'''
== Automotive ==
Radar technology is beign more and more used on automotive safety systems. IGEP RADAR LAMBDA or IGEP RADAR EPSILON can be an interesting first step in order to evaluate the feseability of such systems and the reference design for developing more specialised products.<br>
<br>  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [[Image:AUTOMOTIVE.jpg]]
== Speed Information Display ==
IGEP RADAR LAMBDA or IGEP RADAR EPSILON can be used in combination of a LED&nbsp;Display to develop Speed Information Displays:<br>
<br>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp; [[Image:SPEED.jpg]]
== UAV Altimeter ==
IGEP RADAR LAMBDA and IGEP RADAR EPSILON can be used as short range altimeter for Unmanned Aerial Vehicles.<br>
The estimated range of detection is from 1 to 100meters so, helping on take off and landing of the UAV thanks to the centimeters precission of K-Band radar technology in comparison with the meters precision of traditional 4GHz altimeters used traditionally on avionics.
<br>  <br>  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [[Image:UAVs.jpg]]
== Marine Radar ==
Radar technology is widely used on marine detection systems. Traditional radars use pulsed modulations requiring high RF power levels, affecting power consumption and security of tripulation. FMCW Radar systems are bing more and more used in this application due to its higher precission and its drastically reduced power consumption.
<br>  <br>  <br>  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [[Image:MARINE.jpg]]
== Smart Cities: Intelligent Lighting Systems ==
Radar technology can help to develop intelligent systems for cost and energy savings on Smart Cities systems applications. One example is the Intelligent Lighting System consisting on activation of a row of street lights only when the radar detects a person approaching the area, thus saving lot of illuminating hours with nobody in the street. IGEP RADAR LAMBDA or IGEP RADAR EPSILON could be integrated on this kind of energy efficient systems.<br>  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [[Image:LIGHTING.jpg]]<br>

<br>
Radar technolgy can be also used in several sports where ball speed or trajectory is an important source of information to improve performance. Archers, Tennis and Golf players are becoming more and more dependants on this kind of information in order to improve their techniques.
<br>  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [[Image:SPORT.jpg]]
= Calibration =
Radar calibration can be is done using different techniques. The only way to compare the performance of different radars is by defining an specific test set up in order each radar can be compared in the same conditions. One of the most widely used techniques is based on the use of with special trihedral reflectors. Trihedral reflectors are easy in order to build and stable representing a good reference to be sure the compared radars have the same target reflection characteristicsmeasure its maximum range with precision.   The next pictures show an example of how to make this kind of measurements. First of all you have to find an scenario free of reflections real 70m distance that could disturb the measurements. Ideally you need a free space area of more than 300 meters. Then you put the radar on is able to detect a stable basis and start doing measurements of the signal reflected by the thriedral 20cm trihedral reflector placed in front of the radar. You can start by placing the reflector at 10 meters distance far away from the radar and after that you move it in steps of 5 more meters far away until the radar gets on a signal in the limits of the detection. A threshold of 10dB over the noise signal can be used as a reference. <br>  <br>  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [[Image:TRIHEDRAL REFLECTOR-2ss.jpg]]  <br>  <br>  <br>  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;[[Imagefree space environment:TRIHEDRAL REFLECTORss.jpg]]  <br>  IGEP RADAR LAMBDA detected a 200mm trihedral reflector up to 70 meters range. <br>  <br>  <br>  <br>
