Target detection in Doppler radar with PSK signals

The aim of this article is to test the effectiveness of the known structures of radar signal processing (RSP) that employ CFAR processors in order to detect moving targets in the frequency domain, depending on the chosen width of velocity channels (the number of FFT). The Doppler radar is radar with continuous transmission of PSP (Phase Shift Keying) signals. Real records that have been produced by Doppler radar for the case of moving people or cars on the background of trees are used in the study. The results obtained lead to believe that detection of targets with CA CFAR processors provides the required effectiveness in case when the velocity channel width is correctly defined.
