摘要
文中研究有序统计平均(OSCA)恒虚警检测器在K分布杂波边缘中的性能。推导出该检测器在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,OSGO等检测器进行了比较,结果表明OSCA的抗K分布边缘干扰的性能优于OS,稍逊于OSGO。
The performance of ordered statistic with cell averaging（OSCA） CFAR detector under K-distribution clutter edge situation was studied. The analytic expressions of false alarm probabilities under clutter edge situation were deduced, its performance was anatyzed and compared with OS, OSGO detectors. Results show that the anti-clutter-edge performance of OSCA is better than that of OS, and worse than that of OSGO.
