The Mars Shallow Radar Sounder (SHARAD) is an HF (20 MHz) Sounding Radar embarked onboard the Mars Reconnaissance Orbiter (MRO) spacecraft. SHARAD on-ground calibration activities have been limited to the characterization of the SEB (SHARAD Electronic Box), not having been possible to perform extensive characterization of the flight antenna nor end- to-end calibrations on ground. Scope of the present...
This paper describes the operating principles and the design of the Mars shallow radar sounder (SHARAD), an HF sounding radar devoted to the mapping of sub-surface features of Mars and currently operational on board the NASA/JPL's Mars reconnaissance orbiter spacecraft. Compared to its predecessor MARSIS, currently operating from ESA's Mars Express, SHARAD is characterised by an higher carrier frequency...
