Removal of additive noise in polarimetric eigenvalue processing

This paper concerns with the problem of additive noise in fully polarimetric SAR data. Two approaches - the first one based on conventional four-channel polarimetry and the second one based on polarimetric interferometric data - for estimating and removing additive noise level are presented and discussed. The performance of the proposed approaches is demonstrated using experimental fully polarimetric P-band data acquired by the experimental airborne SAR system (E-SAR) of DLR.
