成像处理一般包括三个步骤：1、距离向脉冲压缩，对一个合成孔径内的每个回波脉冲均进行压缩；2、距离徙动矫正，把属于同一点目标的脉冲校正到等距离线上、3、方位向脉冲压缩。-Imaging process generally comprises three steps: a distance to the pulse compression of echo pulses each have an inner aperture compression　2, range migration correction, the pulses belonging to the same point in the correction target line equidistant , 3, azimuth compression to pulse.
