This document describes the progress on the work performed for Moving Target Detection and Motion Estimation in Foliage Using Along Track Monopulse Synthetic Aperture Radar Imaging, under Contract N00014-96-1-0586, and Signal Subspace processing of Uncalibrated MTD-SARs, under Contract N00014-97-1-0966 for the Office of Naval Research for the period ending on 93098. Our main goal at this stage of the investigation was to test the relative merits of the proposed signal subpace method with a realistic SARISAR database. For this purpose, we utilized the ISAR data of an airborne commercial aircraft the ISAR data were collected by the radar group at the Navys SPAWAR System Center, San Diego. In the first stage of our study, we used the non-overlapping block-based implementation of the signal subspace algorithm for registering two ISAR images of the aircraft which were formed via two separate slow-time segments of the target flight path. We also used the overlapping block-based signal subspace processing to estimate the motion field of the ISAR images. The study with the realistic ISAR data revealed interesting properties of the ISAR signatures of the reflectors, cavities and surface structure for an airborne target.
