sar成像RD算法仿真。可以仿真单点目标和多点目标，可以添加方位向相位噪声-sar RD imaging algorithm simulation. You can emulate a single point and multi-point target goal, you can add azimuth phase noise

点目标成像 基于RD算法的九点目标成像 相干解调形成回波 再距离向压缩 用RD算法最后成像-Point target imaging based on the RD algorithm nine point target imaging coherent demodulation to form the echo and then to the compression of the RD algorithm final imaging
