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,以保证抑制地杂波的同时,减少信噪比损失,提高对弱小目标的检测性能。仿真结果证明该方法是有效的,且在工程上有一定的实用价值。A novel moving target detection filter group design method by building the target processing channel and the weather processing channel is proposed. The target channel can detect clutter in real time by a daptive moving target detection and then auto select weighted factors based on clutter intensity to suppress ground clutter and decrease the loss of signal-noise-ratio, so the performance of small target detection is improved. Simulation results show the method is effective,and it is worthy in engineering.
