Exploiting COSMO-SkyMed spotlight SAR images for GMTI applications

摘要：

The focus of the paper is on the exploitation of COSMOSkyMed (CSK) spotlight SAR images for Ground Moving Target Indication (GMTI). To this purpose two moving target detection schemes are considered: the first is based on a bank of Chirp Scaling Algorithms (CSAs), each one matched to a different relative speed between the radar antenna and the target, and the second is based on Change Detection (CD) applied to sub-images obtained by splitting the overall aperture into sub-apertures. The application of the techniques to Single Look Complex (SLC) CSK spotlight SAR images shows the feasibility of a GMTI mode able to extract medium/high radar cross section moving targets even for single channel spaceborne systems.
