The “long wavelength radar” on the Mars-94 orbiter

Abstract On the Mars-94 mission a long wavelength radar will be deployed on the orbiter for the purpose of probing the surface and sub-surface layers of the planet as well as the top-side of the Martian ionosphere. The radar will permit the study of the structure and electrophysical characteristics of the planetary regolith. The specific goal is to determine the extent and depth of permafrost layers thought to exist. The altitude distribution, the zenith angle variations and the solar wind dependence of the ionospheric electron density will be determined with the same radar for the purpose of assessing the influence of the planetary atmosphere and weak intrinsic and/or induced magnetic fields on the interaction between the planet and the solar wind.
