摘　　要：文章提出一种新的动目标检测(MTD)滤波器组设计方法,即信号处理系统分为目标处理通道和气象处理通道;目标通道采用自适应动目标检测(AMTD)处理方式,实时检测杂波的存在,判定杂波强度(如强、中、弱),根据杂波的强度自动产生或选择滤波器加权因子,以期保证对地杂波高度抑制的前提下,尽量减少信噪比损失,提高对弱小目标的检测能力。该方法可提高雷达在杂波环境中的自适应性能,具有一定的实用价值。This paper introduced the estimation of clutter noise ratio and its application in MTD systemin detail. This method can improvead aptive performance for radar. Final result indicates the method is practical and effective. MTD Technology has been widely used in the radar signal processing. Detection for Moving Targe. The Estimation of Clutter Parameter in MTD SystemThis method can improvead aptive performance for radar. Final result indicates the method is practical and effective.
