摘　　要：针对MLVI-CFAR检测器在多个随机分布干扰目标背景下检测性能不好,以及OSVI-CFAR检测器在均匀环境和仅单滑窗存在干扰目标的环境下检测性能欠佳问题,提出了一种基于删除平均(CML)的VI-CFAR检测器(CMLVI-CFAR)。仿真验证了CMLVI-CFAR检测器在均匀背景及多目标干扰环境下,都具有比MLVI和OSVI-CFAR检测器好的检测性能,并且其在杂波边缘背景下的虚警控制能力与前两者也基本一致,说明其在实际杂波环境中具有更强的鲁棒性和良好的应用潜力。A robust VI-CFAR detector based on censored mean level （termed CMLVI-CFAR） is presented aiming at the problems that the poor detection performance of MLVI-CFAR detector in the situ-ation that the multiple interfering targets are located in reference window stochastically and poor detection performance of OSVI-CFAR detector in the environment of homogeneous or multiple interfering targets on- ly located in leading or lagging halves. The simulation illustrates that in both homogeneous and multiple interfering targets environment, the detection performance of the proposed detector is improved greatly. Moreover, in clutter edge environment, the false alarm performance of this detector is almost consistent with the MLVI and OSVI-CFAR detector. It is more robust than MLVI-CFAR and OSVI-CFAR in prac-tice and has great potential applications.
