The growing interest in achieving a better understanding of the physics that governs the cross-polar scattering of microwave radiation from ocean is triggered by recent measurement campaigns over hurricanes performed by NOAA Hurricane-Hunter winds and RADARSAT-2 [1]. From this data set the cross-polarized signals showed no evident loss of sensitivity as the wind-speed increased from 20 m/s up to 45...
In the last years, in order to investigate the distribution of water in the upper part of the Matianpsilas crust, two different instruments have been developed, and operative up to now: Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) and SHA allow RADar (SHARAD). Both the instruments are low frequency (1.8-5 MHz for MARSIS and 20 MHz for SHARAD) Ground Penetrating Radar (GPR) in...
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...
