摘要：
An FFT (fast Fourier transform) based parametric algorithm, referred to as MCCLEAN, is devised for cross-range phase error compensation in SAR (synthetic aperture radar) imaging. It can be used as an independent autofocus approach for the SAR imaging of a large scene. The authors also present a similarly structured algorithm for simultaneous autofocus and superresolution SAR image formation of a small scene or small region of interest (ROI) in a large scene. Examples are provided to illustrate the performance of the proposed algorithms.
