Abstract
A skewed synthetic aperture radar (SAR) image correction technique based on a back-projection algorithm is presented in this paper. The back-projection algorithm can generally reconstruct a SAR image, including a non-linear flight path, without an additional motion error compensation process. However, typically, the signal distortion owing to the non-linear path remains after reconstructing the SAR image. The skewness of the SAR image can be relieved by a rotated coordinate using an optimum path and a squint-angle compensation. The distortion compensation of the SAR image based on the back-projection algorithm and the proposed deskewing technique were analyzed and verified using simulation and the raw data of the airborne frequency modulated continuous wave (FMCW)-SAR system.
