Cosmo SkyMed AO projects - 3D reconstruction and stability monitoring of the Three Gorges Dam

Cosmo SkyMed is a constellation of Satellites launched by the Italian Space Agency providing Synthetic Aperture Radar images in interferometric mode in X band with a resolution of 3m and revisit time of a few days. In this work, two Cosmo SkyMed datasets of 29 images each, acquired along ascending and descending orbits are exploited for studying the stability of the area of the Three Gorges Dam in China. The short observation time allowed by the short revisit time can generate troubles when distinguishing between seasonal dilation and displacement. Nonetheless, the preliminary analysis clearly highlights movements of the riverbanks around the dam.
