Abstract: This paper concerns the issue of image geometric correction of missile-borne side-looking SAR during its
descending flight. According to the missile flight features, the SAR operation geometric model is presented. Because of the
decrease of altitude during SAR operation, the SAR image is seriously distorted. In this paper, the geometric distortion
correction method for the SAR image obtained by the sub-aperture RD algorithm is proposed. The validity of the method is
demonstrated by simulation.

Key words: synthetic aperture radar, geometric distortion correction, missile borne SAR
