PERFORMANCE OF TWO GENERALIZED ORDER STATISTICS CFAR DETECTORS WITH AUTOMATIC CENSORING TECHNIQUE IN MULTIPLE TARGET SITUATIONS

摘要: 本文提出两种广义修正的有序统计恒虚警(OS-CFAR)检测器和一种自动筛选技术。对这两种新的OS-CFAR检测器,在Swerling 2型目标假设下我们推出了虚警和检测概率及度量平均判决门限的解析表达式。在均匀背景和强干扰目标情况下,文中分析了它们的检测性能,并把它们与几个以前提出的恒虚警处理器进行了比较。

Abstract: This paper presents two generalized modified OS-CFAR detectors and an automatic censoring technique. For these two new OS-CFAR detectors, analytic expressions of the false alarm rate, the detection probabilities and the measure of ADT under the Swerling 2 assumption are obtained. Their detection performances are analyzed in homogeneous background and in the presence of strong interfering targets, and they are compared with several previously proposed CFARs. -
