Abstract

In this letter, we present the first demonstration of the spectral domain polarimetric decomposition concept with an airborne circular synthetic aperture radar (CSAR) dataset. In CSAR systems, radar-carrying aircraft moves along a circular path that encloses the desired target area. The CSAR image contains the scattering characteristics of the target with respect to the azimuth angle, and we can retrieve it by transforming the spatial domain image into its spectral domain representation. Furthermore, the application of polarimetric decomposition to the spectral domain CSAR image provides additional information about the polarimetric scattering mechanisms. We used a publicly released airborne polarimetric CSAR dataset for the demonstration.
