This feature is for advanced measurements and we do not recommend to use on this chapter. It will be explained later.

SECTION-2: RADAR MEASUREMENT
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.
You can see that the default parameters are: -F 3C0000 -s 50 -i 512 -S 80 -m 3. This is the same default modulation used on the Home Menu icons f(t) and F(jw). Now here you can remove these parameters and put what you want.
For example, put in this section the next commands:
-T 800 -m 20
-T 800 means you want a modulation with 0,8ms sweep time
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; [[Image:TECHNICAL-wall-4.8m.jpg]]<br>
The screen shows the result of each of the 20 measurements done on 20 rows, one row per measurement:<br>
<br> 1st column shows the measured target position (4.8m)
2nd column shows the measured target speed (in this case 0Km/h as the wall is no moving)
3rd column shows a value proportional to the measured signal strength.
4th column indicates the delta time between each measurement. In this example the radar did each measurement in only 7ms.
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
    <br>  -w means that you want to write all the captures measurements on a file (there will be generated 16 20 files, one for each measurement, and each one with 2048 samples)
