摘　　要：运动目标检测是合成孔径雷达应用的难题,目标的运动造成图像模糊、错位,给测试造成很大困难。Keystone变换可以校正由于线性距离走动引起的距离和多普勒的耦合,提高动目标检测的性能。仿真结果证实了Keystone变换的有效性。Moving Target Detection is a difficult problem in the application of Synthetic Aperture Radar. Due to the movement of targets, the images are smeard or displaced so that the targets are undetectable. Keystone transform can be used to eliminate the coupling between range and Doppler caused by the linear range migration so that the performance of moving target detection can be improved. Simulation results prove the validity of Keystone transform,
