首先讨论了高斯杂波背景中雷达目标恒虚警检测的原理，然后通过分析慢门限CFAR、邻近单元平均恒虚警（CA-CFAR）检测性能的优劣，提出了改进型CFAR方案，并在计算机模拟统计的基础上对5种处理器的检测性能进行了分析比较，得出对数平均选大恒虚警电路在复杂杂波环境中工作最优，其它各有优越性。

Radar target false alarm detection principle under the Gaussian clutter environments is discussed first .By comparing the detection performance between the slow threshold CFAR and the neighboring cell averaging CFAR (CA-CFAR) .We put forward an improved CFAR algorithm .The detection performances of the five processors are compared with computer simulation ,and the results show that the logarithmic mean false alarm circuits DA HENG election is optimal under the complicated clutter environments w hile the others have their ow n advantages .
