'''<u>If you want to make faster measurements there is a second procedure to follow:</u>'''
open the console and execute this modulationthese instructions:
./radar_init.sh ./radar -r -T 5000 -x 3000 -X 75000 -l 80 -H    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.
 
 
 
Then, you must open the socket on the web server by prompting this address:<br>
 
http://192.168.2.232:8000/realtime.html
 
 
 
Now the radar is ready to make faster measurements and get more than one measurement per vehicle.
 
 
 
<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>
<br> The next graph is the result to orient the radar to another direction, thus increasing the detection range up to 60m.
Note that <bru> '''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.
