In this paper we demonstrate that dc-blocked phase-only filter correlation, based on image sharpening algorithm of SAR images (using an MSTAR data base) for both input and its matching template, is significantly improved. Our approach is tested with a very complicated image using a binary input and a binary matching template. Prior to binarization an image sharpening algorithm is used to enhance the input image and the matching template.
