Abstract
In this paper a method for moving targets detection based on Spotlight Synthetic Aperture Radar (SAR) images is proposed and tested in simulation data. To this purpose two moving target detection schemes are considered: The first is based on a bank of Chirp Scaling Algorithms (CSAs), and the second is based on Change Detection (CD) applied to sub-images obtained by splitting the overall aperture into sub-apertures. At the next step, selecting and arranging target focusing center with a new technique based on re-centering phase computation to a reference point for each moving target. Finally Polar Format Algorithm (PFA) is applied to each re-organized raw data to obtain highly focused moving targets individually.
