Space-based radar systems intended for subsurface sounding of Mars and Moon soils

Abstract

Space-based radar systems intended for investigating the subsurface layers of Mars, Phobos, and Moon are discussed. The characteristics of domestic radar systems developed in preparing the space projects devoted to the study of Mars soils (Mars-96 mission), Phobos ground (Phobos 1 and 2 and Phobos-Grunt missions), and the Moon surface (Luna-Glob mission) are presented. The characteristics of a long-wave Mars advanced radar for subsurface and ionosphere sounding (MARSIS) (Mars Express project) and a long-wave shallow radar (ShaRad) system included in Mars Reconnaissance Orbiter, as well as the results of processing of radar measurement data, are presented.
