Study and characterization of lunar craters using Mini-SAR data of Chandrayaan-1

Abstract

Analyzing lunar surface with various approaches is still a very challenging task. Therefore, in this paper, an attempt has been made to critically analyze the lunar surface by using various approaches so that the possibility of water ice can be predicted. The polarimetric approach helps in determining physical and electrical properties of target. The polarimetric approaches, `m-δ' decomposition and `m-χ' decomposition, have been used for obtaining the information of scattering mechanisms. In order to determine electrical properties of lunar surface, dielectric constant has been measured using Campbell's approach. Then, specular diffuse model has been applied for identifying various craters with reference to surface roughness and possibility of water-ice deposits.
