Now you can move the radar and make measurements over the wall at two different distances. For example, make a measurement with the radar at 2m distance and another measurement with the radar at 5m distance. You should get similar results as the following for 2m and 5m in order:<br>
<br>
MEASUREMENT AT 2 meters (TIME and FFT):

It can be clearly shown how the IF radar signal increases frequency when the target gets more and more distance from the equipment. Look at the increment in periods (frequency) in the time domain signal, and the FFT peak has moved towards higher frequencies.<br>
