Abstract :
The paper presents a method to discriminate ship targets from sea background in focused Single-Look Complex (SLC) Synthetic Aperture Radar (SAR) images. The method is based on Doppler Centroid analysis and it is able to generate an estimate ship velocity. Experimental results are presented showing the application of the method to TerraSAR-X data of the Gulf of Naples, Italy.
