Added a "Dual-polarimetry" tool (Radar -> Polarimetric -> Dual-polarimetry). It includes two new dual-pol indices: Dual-pol Radar Built-up Index (DpRBI) and Dual-pol Radar Surface Index (DpRSI). Additionally, it consists of two methods (decomposition and factorization) to extract scattering power componenets from dual-pol SAR data.
Given the wide availability of dual-pol SAR data from existing and upcoming missions, these operators will be highly valuable for analyzing dual-pol SAR data.
The Microwave Remote Sensing Lab (MRSLab) at IIT Bombay is a leading research group specializing in Synthetic Aperture Radar (SAR) polarimetry and its applications in Earth observation. The lab focuses on developing advanced polarimetric techniques, descriptors, and decomposition methods for various land-cover applications.
Over the years, MRSLab has made significant contributions to the SNAP software by developing and integrating several operators in SNAP, such as the Dual-pol Radar Vegetation Index (DpRVI), the Generalized Radar Vegetation Index (GRVI), the Compact-pol Radar Vegetation Index (CpRVI), the model-free 3-component decomposition (MF3CD), and the model-free 4-component decomposition (MF4C).
