We want to do object detection using the magnitude of the signal.
But we find the absolute value of magnitude can have a really big difference，even in similar environment：
We did range-FFT and showed the data in this image. There are two colors' points，they are both recorded in open places，with only several objects in front of the radar.
So we want to know why the magnitude is so different？Is there AGC module in the radar？
Thanks
