PoSAR: A VHR tomographic GB-SAR system application to snow cover 3-D imaging at X and Ku bands

This paper presents a new Ground-Based SAR (GB-SAR) system, named PoSAR, with tomographic imaging capability at Very High Resolution, over a wide range of carrier frequencies. Some results obtained in the frame of 3-D snow imaging at X and Ku bands are presented and compared to field measurements and electromagnetic scattering simulations.
