Be aware of the radar angle of detection. The radar will only detect objects within its field of view. The angle of detection is about 24º in horizontal direction and about 12º in vertical direction:<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;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; HORIZONTAL: &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <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; [[Image:LAMBDA WIDE ANGLEss.jpg]]&nbsp;  <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;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; VERTICAL:  &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &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:LAMBDA NARROW ANGLEssFIELD OF VIEW.jpg]]<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; <br>
=== Wait few minutes ===
<br>
Congratulations! You have successfully connected with radar. Now you can start to make measurements and learn about radar possibilities. Do not worry if your home page differs from the picture, there are some different format versions and you will have the last one for surebut are equivalent in features.
<br>
== Make your first measurement ==
To see the time domain IF radar signal in real time, you can click on the icon "f(t)": <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; [[Image:WAVE 2m NEWs.jpg]]<br>
Be aware the application demo is designed to work on an environment with only a single target scenario so it is very probably you may see quite different signals than the presented here due to multiple reflections in your room, but this is normal, and this is the ability of radar technology to detect multiple objects at the same time, we encourage you to develop your own application and process the IF signal information to detect not only one but several objects. See next guides if you want to learn more about this. To be sure your radar works well, we recommend you find an adequate environment without multiple reflections before to make any wrong conclusions.<br>
== What is Time domain signal ==
<br>
== Compare Measurements ==
Now you can move the radar and make measurements over the wall at 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 and 5m in order:<br>
<br>  MEASUREMENT AT 2 meters (TIME and FFT):  [[Image:WAVE 2m -T 600 NEWs.jpg]] &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;[[Image:FFT 2m -T 600 NEWs.jpg]]  <br>  <br>  MEASUREMENT AT 5 meters (TIME and FFT):  [[Image:WAVE 5m -T 600 NEWss.jpg]]&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [[Image:FFT 5m -T 600 NEWsCOMPARING_RADAR_MEASUREMENTS.jpg]]<br>
<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. Look at the increment in periods (frequency) in the time domain signal, and the FFT peak has moved towards higher frequencies.<br>
<br>  <br>
== What is "Speed/Range" section ==
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
Each point of the graph is one combined position-speed measurement, position in 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 "Parameters" section ==
This is the most interesting feature of the web application demo. By clicking on "Parameters" icon you will get access to the heart of the radar: &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&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_parameters_NEW.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;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; [[Image:WEB HOME 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>
<br>
=== ===<br>
=== SECTION-4: RADAR MEASUREMENT<br> ===
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] if you want to know more about the meanning of the file names.
 
= Managing Files<br> =
 
IGEP RADAR LAMBDA offers 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 web demo ==
 
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 browswer, 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.
 
<br>
 
<br>
 
== Files using WinSCP ==
 
You have a second 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 do it using the console and using the 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>
 
=== 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:
 
&nbsp;
 
==== Example 1: ====
 
You want to capture 5 consecutive measurement results into a file named measure5.txt. then you must prompt the next command line:
 
./radar -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.
 
<br>
 
Now you can check the measurement results in the generated measure5.txt file, and you will see something like this:
 
&nbsp;&nbsp;&nbsp; Position&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Speed&nbsp;&nbsp; Level&nbsp;&nbsp; Dtime&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; filename<br>&nbsp; [m] +/-0.5&nbsp;&nbsp; [Km/h] +/-3&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; .&nbsp;&nbsp;&nbsp; [ms]&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; .<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 3.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1&nbsp;&nbsp;&nbsp;&nbsp; 417&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 27&nbsp;&nbsp; V70D99999A00.<br><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 3.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1&nbsp;&nbsp;&nbsp;&nbsp; 414&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 8&nbsp;&nbsp; V70D99999A01.<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 3.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1&nbsp;&nbsp;&nbsp;&nbsp; 422&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 9&nbsp;&nbsp; V70D99999A02.<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 3.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1&nbsp;&nbsp;&nbsp;&nbsp; 423&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 9&nbsp;&nbsp; V70D99999A03.<br><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 3.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1&nbsp;&nbsp;&nbsp;&nbsp; 414&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 9&nbsp;&nbsp; V70D99999A04.<br>&nbsp;
 
Where each row shows the result of each of the 5 consecutive measurements, in this particular case it was measured a fixed target at a 3.9 meters distance from the radar.
 
NOTE that it only takes about 9ms time to make each measurement.
 
NOTE also that the file names with the ADC&nbsp;captured data are generated but the files are not saved. They are only saved if you add the command -w
 
<br>
 
<br>
 
==== Example 2: ====
 
You want to capture 20 consecutive measurement results into a file named measure20.txt. In addition you want to use a modulation sweep time of 1,15ms and you also want to generate a file of the ADC captured data for each measurement. Then, in this case, you must prompt the next command line:
 
./radar -T 1150 -m 20 -w &gt;measure20.txt<br><br>
 
Now you can check the measurement results in the generated measure20.txt file, and you will see something like this:
 
&nbsp;&nbsp;&nbsp; Position&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Speed&nbsp;&nbsp; Level&nbsp;&nbsp; Dtime&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; filename<br>&nbsp; [m] +/-0.5&nbsp;&nbsp; [Km/h] +/-3&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; .&nbsp;&nbsp;&nbsp; [ms]&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; .<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -1&nbsp;&nbsp;&nbsp;&nbsp; 866&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 61&nbsp;&nbsp; V70D99999A00.<br><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -1&nbsp;&nbsp;&nbsp;&nbsp; 861&nbsp;&nbsp;&nbsp;&nbsp; 106&nbsp;&nbsp; V70D99999A01.<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -1&nbsp;&nbsp;&nbsp;&nbsp; 839&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 97&nbsp;&nbsp; V70D99999A02.<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -1&nbsp;&nbsp;&nbsp;&nbsp; 846&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 91&nbsp;&nbsp; V70D99999A03.<br><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -1&nbsp;&nbsp;&nbsp;&nbsp; 833&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 92&nbsp;&nbsp; V70D99999A04.<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -1&nbsp;&nbsp;&nbsp;&nbsp; 840&nbsp;&nbsp;&nbsp;&nbsp; 141&nbsp;&nbsp; V70D99999A05.<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -1&nbsp;&nbsp;&nbsp;&nbsp; 864&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 92&nbsp;&nbsp; V70D99999A06.<br><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -1&nbsp;&nbsp;&nbsp;&nbsp; 847&nbsp;&nbsp;&nbsp;&nbsp; 116&nbsp;&nbsp; V70D99999A07.<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -1&nbsp;&nbsp;&nbsp;&nbsp; 836&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 92&nbsp;&nbsp; V70D99999A08.<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -0&nbsp;&nbsp;&nbsp;&nbsp; 816&nbsp;&nbsp;&nbsp;&nbsp; 220&nbsp;&nbsp; V70D99999A09.<br><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -1&nbsp;&nbsp;&nbsp;&nbsp; 818&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 92&nbsp;&nbsp; V70D99999A10.<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -1&nbsp;&nbsp;&nbsp;&nbsp; 825&nbsp;&nbsp;&nbsp;&nbsp; 139&nbsp;&nbsp; V70D99999A11.<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -1&nbsp;&nbsp;&nbsp;&nbsp; 820&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 91&nbsp;&nbsp; V70D99999A12.<br><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -1&nbsp;&nbsp;&nbsp;&nbsp; 825&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 91&nbsp;&nbsp; V70D99999A13.<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0&nbsp;&nbsp;&nbsp;&nbsp; 800&nbsp;&nbsp;&nbsp;&nbsp; 166&nbsp;&nbsp; V70D99999A14.<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0&nbsp;&nbsp;&nbsp;&nbsp; 802&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 90&nbsp;&nbsp; V70D99999A15.<br><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0&nbsp;&nbsp;&nbsp;&nbsp; 802&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 92&nbsp;&nbsp; V70D99999A16.<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 0&nbsp;&nbsp;&nbsp;&nbsp; 807&nbsp;&nbsp;&nbsp;&nbsp; 142&nbsp;&nbsp; V70D99999A17.<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -0&nbsp;&nbsp;&nbsp;&nbsp; 805&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 90&nbsp;&nbsp; V70D99999A18.<br><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -0&nbsp;&nbsp;&nbsp;&nbsp; 810&nbsp;&nbsp;&nbsp;&nbsp; 110&nbsp;&nbsp; V70D99999A19.<br><br>
 
Each of the 20 rows of the measure20.txt file shows the measurement result in range and speed, in this particular case it was measured a fixed target placed at 4.9 meters distance from the radar.<br>
 
NOTE that it takes about 100ms time to make each measurement. This is more than previous example due to now the equipment has to write one file after each measurement.<br>
 
NOTE also that the file names with the ADC&nbsp;captured data are now generated and saved because we have used parameter -w. You should find the 20 generated files in "radar" directory. If you look the contents of one of these files you will see something like this:<br>
 
&nbsp;6384.000000<br>&nbsp;6260.000000<br>&nbsp;6156.000000<br>&nbsp;6083.000000<br>&nbsp;6043.000000<br>&nbsp;6036.000000<br>&nbsp;6047.000000<br>&nbsp;6075.000000<br>&nbsp;6099.000000<br>&nbsp;6107.000000<br>&nbsp;6080.000000<br>&nbsp;6012.000000<br>&nbsp;5888.000000<br>&nbsp;5711.000000<br>&nbsp;5467.000000<br>&nbsp;5164.000000<br>&nbsp;4819.000000<br>&nbsp;4443.000000<br>&nbsp;4056.000000<br>&nbsp;3652.000000<br>&nbsp;3267.000000<br>&nbsp;2903.000000<br>&nbsp;2568.000000<br>&nbsp;2268.000000<br>&nbsp;2008.000000<br>&nbsp;1787.000000<br>&nbsp;1599.000000<br>&nbsp;1439.000000<br>&nbsp;1316.000000<br>&nbsp;1215.000000<br>&nbsp;1135.000000<br>&nbsp;1083.000000<br>&nbsp;1052.000000<br>&nbsp;1048.000000<br>&nbsp;1087.000000<br>
 
...<br>

completing the 2048 samples of each measurement capture
 
The ADC captured files can be used to make your own data processing algorithms.
 
<br>
 
==== Example 3: ====
 
You want to capture 7 consecutive measurement results into a file named measure7.txt. In addition you also want to use a modulation sweep time of 0,9ms and generate a file of the ADC captured data for each measurement. In order to identify your measurements you want to name these files with 12345. Then, in this case, you must prompt the next command line:
 
./radar -T 900 -D 12345 -m 7 -w &gt;measure7.txt<br><br>
 
Now you can check the measurement results in the generated measure7.txt file. You will see 7 rows with the position and speed measured:<br>
 
<br>
 
&nbsp;&nbsp;&nbsp; Position&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Speed&nbsp;&nbsp; Level&nbsp;&nbsp; Dtime&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; filename<br>&nbsp; [m] +/-0.5&nbsp;&nbsp; [Km/h] +/-3&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; .&nbsp;&nbsp;&nbsp; [ms]&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; .<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -1&nbsp;&nbsp;&nbsp;&nbsp; 632&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 48&nbsp;&nbsp; V58D12345A00.<br><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -1&nbsp;&nbsp;&nbsp;&nbsp; 630&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 92&nbsp;&nbsp; V58D12345A01.<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -1&nbsp;&nbsp;&nbsp;&nbsp; 629&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 91&nbsp;&nbsp; V58D12345A02.<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -0&nbsp;&nbsp;&nbsp;&nbsp; 645&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 92&nbsp;&nbsp; V58D12345A03.<br><br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1&nbsp;&nbsp;&nbsp;&nbsp; 619&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 91&nbsp;&nbsp; V58D12345A04.<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.9&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 1&nbsp;&nbsp;&nbsp;&nbsp; 587&nbsp;&nbsp;&nbsp;&nbsp; 149&nbsp;&nbsp; V58D12345A05.<br>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 4.8&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; -0&nbsp;&nbsp;&nbsp;&nbsp; 611&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 91&nbsp;&nbsp; V58D12345A06.<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;
 
If you look in the "radar" directory you will find the 7 data captured files containing the 2048 samples measured by the ADC&nbsp;on each measurement, and these files include the desired extension name: V58D12345A00.txt, V58D12345A01.txt, etc.<br>

IGEP RADAR LAMBDA has been used on this kind of applications, we would like to show you some of the measurements performed.
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:
<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; [[Image:SPEED-RANGE_multitarget-1.jpg]]<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; Real measurements of 4 vehicles tracked in range (orange points) and speed (blue points)
The modulation used to make this measurement was:
-T 5000 -x 3000 -X 75000 -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 75000 -l 80 -H  <br>  radar.init ===&gt; it is necessary only 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 75000 ===&gt; the same as before but applying for far objects, beyond 75m.
<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.
