摘　　要：提出一种新的动目标检测(MTD)滤波器组设计方法,即通过设置目标处理通道和气象处理通道,其中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,根据杂波的强弱自动产生或选择滤波器加权因子,以保证对地杂波抑制的同时,减少信噪比损失,提高对弱小目标的检测性能。通过仿真结果,证明该方法是有效的,在工程上有一定的实用价值。A novel method of designing moving target detection （MTD） filters group is presented, namely setting target processing channel and meteorological processing channel, among which, the target channel adopts adaptive moving target detection （AMTD） processing mode so as to detect the existence of clutter in real time, then the filter weighting factor is automatically generated or selected according to the magnitude of the clutter so as to ensure reducing loss of signal to noise ratio while suppressing the ground clutter, and improve detectability for the low observable target. This method is proved to be effective and practicable in engineering by using the simulated result.
