Scattering Power Components from Dual-Pol SLC and GRD SAR Data

Methods to extract scattering power components and their importance for land cover applications have been extensively studied in radar polarimetry. Motivated by the advancements, this study introduces a novel method to obtain the scattering power components from the dual-pol SLC and GRD SAR data. The idea is conceived from the two proposed indices: DpRBI and DpRSI, that characterize scattering from the built-up (i.e., "dihedral-like") and "surface-like" targets, respectively. These two indices are suitably exploited to obtain the weights for the convex splitting of the total scattered power employing the scattering power factorization framework. The proposed method is applied to dual-pol Sentinel-1 SLC and GRD data acquired over Barcelona, Spain, and Milan, Italy.
