摘　　要：为了更全面地分析CFAR检测器的性能,对线性和平方律两种检波CA-CFAR检测器检测性能优劣问题进行了研究.首先从理论上分别导出了两种检波的最优检测解析式和在CA-CFAR处理时的CFAR损失结果,然后对两种检波方式的检测性能和CFAR损失进行了全面的比较,得到了相应的结论.For the purpose of analyzing fully the performance of CFAR detector, detection performance of CA- CFAR under two modes of linear and square-law detection were studied. First, the optimum detection expressions of the two detectors and their CFAR loss result during the processing of CA-CFAR were derived respectively, then the detection performance under the two detection modes and CFAR loss were compared comprehensively, finally the corresponding conclusions were drawn.
