Simulation of unpolarized scattering in synthetic aperture radar images

With fully polarimetric synthetic aperture radar (SAR), images have been produced from co-polarized, cross-polarized and unpolarized (randomly polarized) scattered signals. From these images, considerable information on scene classification is revealed. Unpolarized scattering is simulated by pairs of scatterers that are orthogonally polarized and located at the limits of range and azimuth resolutions. Sample calculations show that perhaps 10 to 30% of unpolarized scattering is possible.
