*Make first measurements using web server demo application.

Upon completion, you will be ready to continue with chapter 2/3 that explains more advanced tasks.

__TOC__

= Requirements =

In this tutorial we are going to use the following materials:

* IGEP RADAR LAMBDA with its power supply* Network cable* PC with keyboard, mouse and monitor

<br>

= Getting started =

Please follow the next steps as indicated. You could change later the way you use the radar but it is very important you follow these instructions at least once for the first time:

<br>

== Place the Radar on a stable surface ==

== Place the Radar on radar over your desk and oriented with the ORION board (antenna) facing a stable surface ==wall of your office with nothing in between. A distance of about 3 meters between the radar and the wall would be good to make the first measurement.

Place the radar over your desk and oriented with the ORION board (antenna) facing a wall of your office with nothing in between. A distance of about 3 meters between the radar and the wall would be good to make the first measurement.<br>

== Network ==

== Network == You may now plug the Ethernet cable into the 10/100 Ethernet jack of the IGEPv2 board of the radar to get network access. The default firmware configures the Ethernet device with static ip address (192.168.2.232). Start your PC and plug the Ethernet cable to it.

== Source Power ==

<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:RADAR ON TABLE SET UPs.jpg]]

== Wait few minutes ==

Once you apply power, please wait a few minutes while IGEPv2 board boots with the default firmware flashed on the internal memory. You will see LEDs from IGPv2 board blinking until system has booted, then you will see a fixed lighted green LED.

== Run Web Browser on PC ==

Run a web browser on your PC with the ability to work with gnuplot4.6. We recommend the use of "Mozzilla FireFox" web browser that you can install and download for free at: http://www.mozilla.org/en-US/

== Connect to Radar IP ==

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 power of the radar 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>

<br>

 <br>

== What is Time domain signal ==

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&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]]<br>

== What's 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; &nbsp; &nbsp; &nbsp;&nbsp;&nbsp; [[Image:WEB-WAVEwhatsthis.jpg]]

== Basic FMCW Radar Theory ==

So, if the measured IF radar signal frequency is 4,609KHz it means the target is at a distance of 3,6m from the radar.

Considering the radar has an offset of about 0,35m (we will see later whythis is due to the microwave signal has this electrical lenght internally on the equipment before to reach the antenna) the distance is real results in 3,25m<br>

== What is Frequency domain signal ==

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 ==

It can be clearly shown how the IF radar signal increases frequency when the target gets more and more distance from the equipment.

<br>

<br>

== Real Time ==

Each point of the graph is one combined position-speed measurement, position in orange 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.

== Technical ==

-T 1000

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.

== Files ==

Check the user manual of IGEP RADAR LAMBDA if you want to know more about the meanning of the file names.<br>
