| Summary: | Abstract – Polarimetric data acquired by the CCRS CV-580 airborne SAR is used to assess the capability of RADARSAT-2 for operational sea ice classification. The information content of the polarimetric data is illustrated by showing how specific scattering mechanisms are portrayed by the entropy, anisotropy and α-angle features. Ice type classes are derived from the full pol data set using a complex Wishart classifier. The classes are then mapped into 2-D scatterplots to compare the information content between dual and fully polarimetric data. While dual pol data is an improvement over single channel data, it is found that fully polarimetric data is needed to provide accurate ice classification performance. I. |
