The application of Independent Component Analysis (ICA) on SAR images has given satisfactory results, with specific usefulness and applicability in cases of processing without ground-truth and detailed atmospheric-data availability. In particular, the extraction of geophysical information has been obtained and verified in cases of single-polarization multi-pass ERS-1/ERS-2 SAR images (e.g., Ballatore, Proc. of FRINGE 2007 Workshop, ESA SP-649, 2008) . The application of ICA technique on multi-polarization SAR data is expected to provide several additional potentialities. This paper describes these potentialities, with specific reference to the case of RADARSAT-2 parameters. Considering that some experimental findings are already available about ICA application on quad-pol PALSAR data, the extension of this applicability on RADARSAT-2 images is detailed, together with the importance of the supplementary geophysical information that will be derived. Some results obtained on RADARSAT-2 simulations are presented.
