Measurements of a person approaching by walking slowly the radar were made during 7 seconds, capturing 1.000 measurement files.
The modulation used was: -T 1600 -m 1000 -w
This modulation means:
-T 1600 ===> > program modulator with a 1,6ms modulation sweep time
-m 1000 ===> > make 1000 consecutive measurements
-w write ===> > and save the captured data into text files
<br> The 1.000 measurement files were captured and processed later with matlab. FFT was made for each measurement obtaining the next 2D plot:

Y axis : represents twice the distance<br>
X axis : represents the measurementfile number (so it can be considered as time)<br>
It can be noted that the person is detected from about 18m in the first measurements and is moving to towards the radar until 14m distance in the last measurements. <br>
