摘要 本文首先给出了多普勒信号的模型,然后简单分析了壁滤波器设计以及无需滤波的AR模型法。重点分析了可用作壁信号抑制的不同滤波器形式并初步比较了其性能。 The model of Doppler signal was constructed at first,then the design of wall filter and AR Models of unneeded filtering clutter were analyzed and various filter that can suppress wall signal were mainly analyzed and their capability were compared simply in this paper.
