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 the first 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.

-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>

Then, you must open the socket on the web server by prompting this address:<br>

http://192.168.2.232:8000/realtime.html

<br>

Now the radar is ready to make faster measurements and get more than one measurement per vehicle.

Now the radar is ready to make faster measurements and get more than one measurement per vehicle.<br>

  <u>'''Note that each application needs to optimise its own parameters'''</u>. You can tune the parameters in order to adapt better to your application. For example you may be will get better results if you use a different modulation sweep time, may be -T 6000 is better for your application. Just try and get the best configuration for you, this is one of the purposes of the radar evaluation board.

<br>

The next graph is the result to orient the radar to another direction, thus increasing the detection range up to 60m.

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.
