Abstract
Aiming at InISAR imaging of dechirp data under squint modela new method based on squint iteration optimization (SIO) and distortion correction (DC) is proposed in this paper. The squint model induces the influence of accessional phase and image distortion. The 3D imaging results degrade seriously when the squint angle is big. Through a few times of squint iteration optimization and distortion correction, the estimation precision and the imaging quality are improved. Simulation results demonstrate the effectiveness of the method.
