The dielectric permittivity of terrestrial ground ice formations: Considerations for planetary exploration using ground‐penetrating radar

摘要: [1] Exploration of the polar ice caps and apparent glacial periglacial landforms on Mars will aid our understanding its ancient climate conditions history water planet. Given that ground-penetrating radar (GPR) is likely to be used understand these features, we investigated real component complex dielectric permittivity stratified segregation ice, non-stratified polygonal wedge deposits in Canadian Arctic. We acquired moveout profiles with a 450 MHz GPR ground formations had active layer sediments excavated prior surveying. Using core data collected from sites, found volumetric fraction plays greatest role defining deposit it can described using modified refractive index method (CRIM) mixing model. CRIM model, estimate several Earth present further estimates for similar features values Martian derived both theory laboratory methods.
