Abstract :
Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) is a low frequency, pulse-limited radar sounder and altimeter selected by ESA as a payload of the Mars Express mission. This work retraces the processing that leads to the extraction of parameters needed to perform the data inversion pointing out an effect caused by the weighting network application in presence of volume scattering that could jeopardize the backscattering-related geometry interpretation on a specific set of data.
