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

摘要: 本文提出兩種廣義修正的有序統(tǒng)計恒虛警(OS-CFAR)檢測器和一種自動篩選技術(shù)。對這兩種新的OS-CFAR檢測器,在Swerling 2型目標(biāo)假設(shè)下我們推出了虛警和檢測概率及度量平均判決門限的解析表達式。在均勻背景和強干擾目標(biāo)情況下,文中分析了它們的檢測性能,并把它們與幾個以前提出的恒虛警處理器進行了比較。

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. -
