CFAR Different Schemes Behavior and Detection Performance of Moving Targets

摘要

In this paper detection probability of different CFAR schemes CA, GO, SO, and OS-CFAR is computed via various values of false alarm probability. The CA-CFAR and GO-CFAR detection performance is superior over other schemes; OS-CFAR detection performance appears to be the quasi of CA-CFAR but needs more processing time than CA-CFAR. Moving target detection is investigated Each of the CA, GO, OS-CFAR schemes gives acceptable detection probability at higher values of SNR and gives, as well, maximum performance in the range of 10~(-4) to 10~(-6) probability of false alarm. The SO-CFAR scheme doesn't offer any advantage over other CFAR processors.
