| 摘 要： | 动目标显示(MTI)技术是雷达在杂波环境中发现运动目标的有效手段。首先讨论了雷达信号处理中常用的自适应动目标显示技术,即在多杂波环境下的自适应杂波抑制技术。然后针对雷达杂波抑制中常用的级联MTI滤波器,提出了一种新的设计方法,即采用时变加权原理,通过对动杂波速度估值,实现对运动杂波抑制滤波器权值的优化。最后给出了这2种杂波抑制级联型MTI的工程实现。

| Abstract: | Moving Target Indication MTI is an effective measure which radar detects moving targets in clutter interference environment.First of all,the ordinary adaptive MTI techniques in radar signal processing are discussed,the approach to adaptiveclutter rejection in multiclutter environment is analyzed in this paper.Secondly,a new method based on timevarying weighted MTI filters is proposed.The weighted value of moving clutter rejection filter is optimized by estimating the velocity of moving clutter.Finally,the optimized and cascaded MTI filter rejecting static and moving clutter is provided in engineering. |
