说明：  SAR成像RD算法MATLAB仿真，其中核心部分在于距离弯曲（徙动）校正 -- RCMC以及距离压缩后数据、距离压缩后距离多普勒域、距离压缩后距离多普勒域、未进行距离徙动校正后的距离方位压缩结果、透视校正后的最终结果
(The SAR imaging RD algorithm MATLAB simulation, in which the core part is that the distance bending (migration) correction- RCMC distance compressed data, compressed distance from the Doppler domain, range compression range Doppler domain, not the range migration final result after the compression result, after correction of the distance and orientation perspective correction)
