摘　　要：为满足雷达仿真系统抑制杂波、提高雷达信号的信杂比以利于运动目标检测的研究需要,分析了MTI常用的延迟线对消器,针对其存在的不足,建立了基于特征矢量法的MTI滤波器的几何描述模型,并通过仿真对比验证了基于特征矢量法的MTI滤波器的优越性和可行性。For the need of the clutter suppression in the simulation of radar system and the need of the improvement of the radar signal SNR to detect moving target,it analyzeds the commonly used delay line cancellation in MTI. Aiming at the disadvantage and shortage, it establisheds a geometric model based on the eigenvector method,and through comparing the simulation,it validated the feasibility and superiority of the eigenvector method.
