%X SAR echo signal in high squint mode features large range walk and small range curvature. An improved CS imaging algorithm based on range-walk removal is proposed. First, range-walk is removed in time domain. Second, range curvature is corrected in frequency domain. Finally, geometry correction is used to correct geometric distortion. The coupling between azimuth and range is greatly reduced after range-walk removal. Therefore, it satisfies the imaging quality of SAR in high squint mode and the width of the scene swath is broadened as well. Simulation results illustrate that it satisfies the imaging quality of SAR in high squint mode and large scene swath.
