通过分析现有的五种恒虚警率 (CFAR)处理器检测性能的优劣 ,提出了两种改进型CFAR方案 ,并在计算机模拟统计的基础上对七种处理器的检测性能进行了分析比较 ,得出准选大恒虚警率 (PGO CFAR)和准有序恒虚警率 (POS CFAR)是两种较为实用的在复杂杂波环境中工作的恒虚警处理方案 ,且各有优越性。

In this paper, two kinds of modified CFAR processor are proposed through discussing the advantages and disadvantages of five kinds of existing CFAR processors. Based on the computer simulation and statistics, detection performance of seven kinds of CFAR processor have been analysed in this paper, and it has been proved that the PGO CFAR and the POS CFAR processor are more useful CFAR processors in the working environment of complex clutter and each has its own advantages.
