穿墙雷达成像中墙体回波抑制

Suppression of Wall Echo in Through-the-Wall Radar Imaging

在穿墙雷达成像应用中,墙体作为稳定的强散射体存在,对目标回波信号造成严重干扰.该文针对静止目标成像,提出用墙体回波估计后对消和滤波器滤除墙体回波的方法来抑制墙体回波,并仿真验证.另外提出墙体图像提取对消和多视角图像融合对墙体回波抑制的可行性.

In the application of through-the-wall radar imaging,as a steady scatter,the wall cause serious interference to the target echo.In this article,aiming at static target imaging the simulation of wall echo estimated cancellation and wall echo filtered by filters are realized.And put forward the feasibility of the solutions of wall imagine extraction cancellation and wall echo filtered by filters.
