%X Spotlight SAR is an efficiency way to obtain high resolution radar image. The non-stability of the aircraft motion during the long synthetic aperture time can make the image suffer the severe defocus, and there is phase error in the range direction in the high resolution SAR system. This paper presents a novel signal processing method based on echo signal to get high definition resolution spotlight SAR image, which can make an effective estimation on the aircraft position error, the phase error in range direction and the residual envelop error. The experiment results show that the proposed approach can get the high quality SAR image from raw data.
