A new method of imaging low-altitude moving target with spotlight SAR based on stripmap SAR data is presented, which combines the wide area searching ability in stripmap SAR mode with advantage of less computation load in spotlight SAR. Firstly, after the ground (sea) clutter in strip map SAR data is suppressed, the moving target possible appearing area is found, and the range compression is finished, then the moving target is aligned in envelope. Secondly, to the moving target possible appearing area, the stripmap SAR data is transformed into the spotlight SAR data. Thirdly, to the spotlight data being transformed, the moving target imaging is completed after the motion compensation to the imaging scene center is done. Simulation has verified the validity of this method. ;
