滑动聚束模式的RD成像。聚束模式SAR中,天线始终指向场景中心,合成孔径的长度比相同条件下的条带式SAR长。对于滑动聚束模式SAR系统,由于天线的指向变化与两者都不同,所以与条带模式相比,其合成孔径更长,而且测绘带区域比聚束模式更大 -The Sliding Spotlight model described in the article can geta better resolution than strip-map mode and better observed area than

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
