Automatic motion compensation using the registration-restoration-fusion technique

A novel toolbox is developed to perform automatic target translational and rotational motion compensation for ISAR imaging. The method is based on an automatic registration-restoration-fusion technique. 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/after restoration processing could be used to generate the focused ISAR image.
