Abstract

The Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) and the Shallow Radar (SHARAD) are currently operating on Mars transmitting an HF chirp signal to retrieve information regarding the Martian crust structure. An important task to be performed is the data inversion, i.e., the permittivity estimation of the detected subsurface layers. In order to be properly performed, degrading effects on attenuation estimation and geometric term correction have to be understood. This paper aims to simulate a few representative scenarios, using the Finite-Difference Time-Domain formulation, pointing out the volume scattering influence on MARSIS and SHARAD data. Influence on both attenuation estimation and geometric term correction will be discussed.
