Abstract :
The aim of this work is the development of processing techniques in order to provide the Cosmo-SkyMed (CSK) single-channel SAR system of Ground Moving Target Indication (GMTI) capabilities. To this purpose a two step processing chain is proposed: the first step performs stationary clutter suppression while the second step performs moving targets detection. For the last step two different detection schemes are proposed based respectively on a Bank of Chirp Scaling Algorithms (BCSA-MTD) and on a Change Detection approach (CD-MTD). The effectiveness of the proposed techniques is demonstrated against CSK data.
