Abstract

This paper is addressed to the improvement of the range resolution of MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding) by means of a modified version of the stepped frequency processing algorithm. MARSIS is a low frequency, pulse-limited radar sounder and altimeter selected by ESA as a payload of the Mars Express mission. The ionosphere affects MARSIS operation in terms of phase distortion, attenuation and Faraday rotation. The ionosphere fine compensation is obtained according to the uniform model, allowing, with the correctly compensated data, the production of MARSIS images at higher resolution. In this way it is possible to detect hidden interfaces never seen before due to MARSIS coarse vertical resolution. © 2011 IEEE.
