| Abstract: | In this paper,the basic principle of three kinds of two-sample nonparametric CFAR detectors was introduced and their detection performance was study under real sea clutter by comparing with CA-CFAR detector,where the statistical property of this real data was unknown.The analysis results showed that,under the strong sea clutter the GS-CFAR detector had the best performance and under the weak sea clutter the Savage-CFAR detector has the best performance.The three kinds of two-sample nonparametric CFAR detectors had distinct advantage in detecting and suppressing sea clutter over the CA-CFAR detector. |
