Mars north polar cup subsurface materials property estimation using GPR SHAllow RADar data

摘要

Since September 2006 SHARAD (SHAllow RADar) is mapping the distribution of water, liquid and solid, in the upper portions of the Martian crust, the SHAallow RADar (SHARAD) is active. Upon the instrument data acquisition an appropriate processing has to be performed to discriminate the Martian subsurface echo from the surface one. The detected subsurface signal is then processed with a dual frequencies techniques in order to estimate the materials loss property. Using the system parameters the surface material dielectric constant can be evaluated. Finally, using a data inversion procedure the subsurface material property of the Mars subsurface are estimated by taking into account the geometric clutter contribution.
