Polarimetric ISAR autofocussing techniques: Comparison of results

Abstract

This paper briefly describes a number of scalar, partially polarimetric, and fully polarimetric ISAR image autofocusing approaches that are based upon the PPP and ICBA autofocusing techniques. All approaches are then compared and contrasted using real world data provided by the Defence Science and Technology Organisation of Australia. From this analysis the ICBA approach results in an improved image focus as defined by the image contrast, image entropy and image peak measures, whereas the performance of the PPP based approaches are mixed at best.
