Inversion of dielectric properties of Lunar PSR regions using UHF radar range pol-echoes

Radar range echoes of the UHF radar souder is presented to explore the lunar surface in the permanently shdaowed polar regions (PSR). Based on radiative transfer with the Euler-angles transformation, the temporal Mueller matrix to take account of all scattering mechanisms of undulated rough surface and underlying scatter media is derived. It is applied to invert the dielectric constant of PSR region for water ice detection.
