My research work involves mapping subsurface hydrological and geological structures in planetary arid and cold-climate environments using radar imaging and sounding techniques. The study covers two potential applications. The first is to evaluate the potential of low-frequency orbital sounding and ground-penetrating radars to map the possible presence of Martian subsurface hydrological features, such as local water lenses or aquifer systems. The approach includes electromagnetic characterization of Martian-like materials,materials; numerical simulations of wave propagation in geo-electrical models, GPR field surveys, and comparative planetology studies. The second main point of interest concern the use of radar techniques to explore heavily eroded and dust covered geological feature in order to trace large-scale subsurface stratigraphy and structures. This includes the mapping of impact craters, paleo-hydrological drainage networks and volcanic features such as rifts, lava tubes and flows.
The basic elements of this research can be summarized by the following:
-Electromagnetic characterization of Martian-soil analogues -Mars Ground Penetrating Radar analogue studies -Numerical simulation of the wave-soil interaction
