Abstract :
The following paper concerns preliminary results from a phenomenological analysis of vessel scattering carried out on Synthetic Aperture Radar Spotlight data. Time-frequency analysis tools have been applied to real data acquired from the German satellite Terrasar X, in order to detect and characterize the different scattering mechanisms contributing to the received signal. The impact and correction of data perturbations due to the motion of the ship are also discussed.
