PERFORMANCE ANALYSIS OF TWO CFAR DETECTORS UNDER CLUTTER EDGE SITUATION
两种恒虚警检测器在干扰边缘中的性能分析

This paper studies the performances of the GOSGO (Generalised Order Statistics and Greatest Of)- and GOSSO (Generalised Order Statistics and Smallest Of)-CFAR detectors under clutter edge situation. The analytic expressions of false alarm probabilities under clutter edge situation are derived. Their performances to counter clutter edge are analysed, and compared with those of the OS(Order Statistics), CA(Cell Averaging), GO(Greatest Of) and SO(Smallest Of) detectors. The results show that GOSGO possesses better performance than GO for countering clutter edge. But the performance of GOSSO is not good.
