ISAR Motion Compensation using the Registration-Restoration-Fusion Method

Abstract

A new method is developed to perform target translational and rotational motion compensation for ISAR imaging. The method is based on a registration-restoration- fusion technique. This technique provides an efficient method to resolve the image smearing caused by the time-varying behavior of the target scattering centers and leads to a well-focused ISAR image. The basic idea is to use the nearest neighbor method to obtain control points and estimate motion parameters from two or more candidate images. The registration processes use these estimated motion parameters to remove both translational and rotational motion. The restoration process may be used to eliminate the blur that is induced by the registration process. Furthermore, the fusion of two registered images before or after restoration processing could be used to generate the focused ISAR image. This proposed method has been successfully applied to both experimental and simulated ISAR data.
