摘　　要：研究有序统计选大(OSGO)恒虚警检测器在K分布杂波边缘中的性能。文中推导出了该检测器在K分布杂波边缘中虚警概率的解析表达式,分析了它抗干扰边缘的性能,并与OS、CA、OSSO等检测器进行了比较,结果表明OSGO-CFAR具有最好的抗K分布杂波边缘的性能。The performance of the Ordered Statistic with Greatest Option CFAR（OSGO-CFAR） detector in K-distribution clutter edge is studied. The analytic expressions of false alarm probabilities in K-distribution clutter edge and its performance against the clutter edge is analyzed. The OSGO-CFAR detector is compared with the OS, CA and OSSO detectors. The results show that among these detectors the OSGO-CFAR detector has the best performance against the K-distribution clutter edge.
