Electromagnetic propagation modeling for GPR exploration of Martian subsurface

摘要

This work presents a study on possible subsurface models for GPR exploration of Martian soil. In particular, based on recent experiments, the electromagnetic properties of Mars soil simulants are reported and relevant GPR performance is calculated in different frequency ranges through a one-dimensional transmission-line propagation model. The presence of statistically-distributed inhomogeneities inside soil is also taken into account by calculating their scattering and attenuation features.
