Abstract :
Several signal processing techniques are presented and evaluated to filter/enhance SAR digital elevation models (DEMs). The results are compared to a topographic digital terrain model (DTM) in the context of 3D visualization and real-time rendering. Through the DLR X-SRTM DEM, the interest of InSAR data for such applications is illustrated.
