This possibility is estimated as a magnitude of SNR at the input of the signal detector calculated depending on the frequency of reception, the size of airplanes, which are crossing the baseline of FSR at the approximately right angle and the distance from the receiver to airplanes.enforward scatter effectFraunhofer diffractionFSRtarget detectionConference Paper10.1109/RadarConf2043947.2020.9266428Other
