Evaluation of multi-polarization SAR data at L-, C- and X-band for sea-ice monitoring in the Baltic Sea
SAR data from the satellites ALOS, Envisat, Radarsat-2 and TerraSAR-X were compared in order to evaluate their usefulness for sea ice monitoring in the Baltic Sea. Different advantages and disadvantages were identified for the SAR systems and imaging modes. It has been shown that cross-polarized dat...
