Abstract：The paper concerns the error analysis of image geometric distortion correction for missile-borne side-looking SAR. Because of the decrease of altitude during SAR operation, the SAR image obtained by common used imaging algorithm is seriously distorted. In the paper, the geometric distortion correction method of the SAR image related to subaperture RD algorithm is presented. Especially, the errors of geometric distortion correction are analyzed. The effectiveness of the method and error analysis of the geometric distortion correction are demonstrated by simulation.
