Do you know if the receiver function of “usrp_radar_mono.py” is complete?
If yes,where are the datas ,which are recovered by the receiver, store ? And
how can I get them back?

The gr-radar-mono transceiver records, during the programmed range
gate, the raw echo returns in a complex baseband format. You will
need to post-process these using your algorithm of choice.
