Shallow subsurface sounding from a rover with a polarimetric GPR
Abstract
The WISDOM GPR has been designed, for the ExoMars 2018 ESA mission, to investigate the Martian near subsurface down to a depth of a few meters with a vertical resolution of a few centimeters. WISDOM is a step frequency radar operating over a wide frequency band between 0.5 and 3 GHz. Particular attention was paid to the design of the antenna system, which needs to be able to conduct polarimetric measurements. The work presented focuses on the capacities provided by these polarimetric measurements
