Urban Area Characterization Using 2-D and 3-D Spaceborne PolSAR Data

This paper addresses some advanced PolSAR approaches combined with time-frequency and tomographic techniques for characterization of urban areas. Three case studies are dedicated to demonstrate the effectiveness of these polarimetric approaches, using spaceborne SAR data such as Sentinel-1, RadarSAT2 and TerraSAR/Tandem-X. The results show advanced PolSAR approaches can provide a refined characterization of urban areas from space.
