摘要
针对在多目标、强干扰非均匀环境下CA-CFAR、OS-CFAR检测器的检测性能严重下降的问题,本文提出一种基于检测单元统计特性来选择参考单元的CFAR。分析结果表明,相比于CA-CFAR、OS-CFAR,该CFAR在均匀环境中具有较小的损失,在非均匀环境中,具有较强的抗干扰能力。
A kind of constant alarm rate （CFAR） whose reference unit is selected on basis of statistical characteristics of detecting unit is presented in view that the detection performance of CA-CFAR and OS- CFAR detectors decrease seriously under multitarget, intensive interference, non-uniform environment. The analyzed result shows that this CFAR loses less under uniform environment and has stronger capability of anti interference comparing with CA-CFAR and OS-CFAR.
