Real Representation of the Polarimetric Scattering Matrix for Monostatic Radar

Synthetic aperture radar with polarimetric diversity is a powerful tool in remote sensing. Each pixel described by the scattering matrix corresponding to emission/reception polarization states (usually horizontal and vertical). The algebraic real representation, block symmetric form, introduced adopt more comprehensive framework (non-restricted reciprocity assumptions) mapping consimilarity equivalence relation. proposed representation can reveal potentially new information. For example, its eigenvalue decomposition, which itself necessary step obtaining transformation products, may be useful characterizing degree of reciprocity/nonreciprocity. As consequence, it employed testing compliance assumed monostatic PolSAR data. Full-wave simulated data confirm that oriented scatterers present complex eigenvalues, even geometry.
