Simulation study of azimuth resolution for SAR imaging through Chirp Scaling Algorithm using MATLAB

Resolution holds an important significance in images produced by Synthetic Aperture Radar (SAR). The clarity and feature identification of an image varies both with range and azimuth resolution parameter of SAR. The majority of resolution improvement in an image formed using SAR depends largely on antenna size of the radar. In this paper a comparative study of various images using Chirp Scaling Algorithm (CSA) is done by varying antenna size. The Simulation studies have been carried out on real earth image using MATLAB platform.
