Adaptive Scan-On-Receive Based on Spatial Spectral Estimation for High-Resolution, Wide-Swath Synthetic Aperture Radar”, to be published

Abstract

ABSTRACT In this work we investigate the possibility of applying direction of arrival (DOA) estimation methods to highresolution, wide-swath Synthetic Aperture Radar (SAR) spaceborne systems, based on Scan-On-Receive (SCORE) technique. Spaceborne SAR for remote sensing applications is experiencing a golden age, as testified by the number of the recent and forthcoming missions, e.g. ALOS PALSAR, TerraSAR-X, COSMO-SkyMed, RADARSAT-2, TanDEM-X, Sentinel-1. Nevertheless, the current generation of spaceborne SAR sensors suffers a basic limitation: it does not allow for high resolution imaging and, simultaneously, wide coverage Main characteristics of SMART SAR systems are the use of multiple transmit/receive channels and the introduction of digital signal processing techniques in the conventional SAR processin
