Analysis of SAR Imagery with different Data Processing Algorithms and Comparison thereof

Abstract

A microwave synthetic aperture radar (SAR) system is used for very high resolution imaging purpose. In this paper the authors formed SAR images with Doppler Beam Sharpening (DBS) algorithm, Range Doppler Algorithm (RDA), Chirp Scaling Algorithm (CSA) and Omega-K Algorithm (ωKA) using ERS satellite SAR data, and are analyzed by measuring the Impulse Response Function (IRF) of a point target in the images. The results are summarized and compared.
