摘要: 针对MIMO雷达的体制特点，该文提出了两种有序统计与均值相给合的MIMO雷达CFAR检测器(OSCA- CFAR和LCIOSCA-CFAR)，给出了虚警概率与检测概率的表达式，然后在各种杂波背景下对检测器性能进行了仿真分析，并与经典的CA-CFAR检测器进行比较，仿真结果表明，OSCA-CFAR和LCIOSCA-CFAR检测器在均匀背景下较CA-CFAR有较小损失，在多目标干扰环境较CA-CFAR性能改善明显，在实际背景中具有更强的鲁棒性。最后比较了OSCA-CFAR和LCIOSCA-CFAR检测器的优缺点。Abstract: Based on the system characteristics of MIMO radar，two kinds of MIMO radar CFAR detectors(termed OSCA-CFAR and LCIOSCA-CFAR) based on order statistic and mean level are presented. Firstly, formulas of false alarm probability and detection probability are given. Then detection performance under various clutter background is compared with classic CA-CFAR by simulating and analyzing. The simulation results show that performance of OSCA-CFAR and LCIOSCA-CFAR has a low-loss under uniform clutter and is improved greatly under multi-target interference compared with the CA-CFAR. So it is more robust than the CA-CFAR in practice. Finally，advantage and disadvantage of the two kinds of CFAR detector are indicated．
