Abstract :
In this paper, we propose a polarimetric TomoSAR method with Wiener-SVD inversion and Gerschgorin Disks for different scattering mechanisms of each point. Seven images of RADARSAT-2 Fine Quad Mode have been used to validate the efficiency of the proposed method. The polarimetric analysis shows that more scattering points can be detected by the composition of different polarimetric bands, thus retrieving more information on the elevation within one resolution cell.
