Abstract
The paper presents a relaxation-based autofocus (AUTORELAX) algorithm that can be used to compensate for the aperture errors in curvilinear synthetic aperture radar (CLSAR) and to extract three-dimensional target features. A self-contained detailed derivation of the data model for the autofocus prob lem in CLSAR is presented. Experimental and simulation results show that AU TORELAX can be used to significantly improve the estimation accuracy of the target parameters.
