Polarimetric Decomposition Analysis of Lunar North Pole Crater Hermite-A Using Chandrayaan-2 DFSAR Data

Chandrayaan-2 launched in the year of July 22, 2019 consisting of different types of sensors to map the lunar surface. It integrates Synthetic Aperture Radar (SAR) at two wavelengths (L and S band) at various resolutions with numerous polarimetric ways in a lightweight configuration (about 20 kg). The computation of the 2×2 complex scattering matrix for each resolution cell can be obtained from the DFSAR (Dual Frequency Synthetic Aperture Radar) which enables the characterization of the lunar surface at different incident angles, wavelengths in terms of polarization properties of the radar. This paper mainly focuses on various decomposition techniques and analysis of backscattering coefficients of the lunar surface using full polarimetric L-band DFSAR data. The data is collected from PSR (Permanent Shadowed Region) of lunar north polar Hermit-a Crater.
