| 摘 要： | 本文研究 GOSGO(Generalised Order Statistics and Greatest Of)和GOSSO(Generalised Order Statistics and Smallest Of)-CFAR检测器在干扰边缘中的性能。文中推导出了它们在干扰边缘环境中虚警概率的解析表达式,分析了它们抗边缘干扰的性能,并且与OS(Order Statistics)、CA(Cell Averaging)、GO(Greatest Of)和SO(Smallest Of)等检测器进行了比较。结果表明,与抗边缘干扰性能较好的GO相比,GOSGO的抗边缘干扰性能又有明显的增强。但是,GOSSO的抗边缘干扰性能却很不理想。

| Abstract: | 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. |
