Abstract : Urban growth monitoring is a demanding task that can be supported by SAR imagery given the resolutions of the new generation of spaceborne sensors. Polarimetry improves target characterization at the expense of the resolution. To overcome this difficulty, we designed a resolution enhancement solution based on a spectral ap- proach. The developed algorithm aims to focus point tar- gets while preserving their polarimetric responses. Re- sults are illustrated on the city of Toulouse. The images used are 2007 PolInSAR Ramses acquisitions. Isolated bright point-like scatterers are correctly focused and con- serve the full polarimetric features
Keywords : SAR resolution enhancement polarimetry bright scatterers point-like scatterers.
