Abstract：In order to obtain a UAV SAR image of high quality,a method is proposed to compensate the motion errors of UAV by virtue of the analysis of its motion errors.In our method the attitude errors are compensated through an antenna servo system.Based on the established error model the position errors are estimated by the instantaneous Doppler chirp rate from the SAR raw data and compensated through the envelope correction and the phase correction of the raw data,respectively.The experiment results show that the proposed approach can get the high quality SAR image from the UAV SAR raw data.
