ABSTRACT: At present, an
investigation of the lunar ground at great depths is of paramount importance.
This investigation can be carried out using decameter and meter waves. This
article aims to analyze the variations of the reflectioncoefficientatdecametric,meter and decimeteric bands.Apossibility
of determinationof lunar ground
characteristics by bistatic radar using powerful ground-based transmittersat VHF and UHF bands and a receiver
aboard aMoon’s satelliteis analysed. Appropriate algorithms
are considered for determinationof the regolith layer thickness,dielectric permittivity, loss tangent,
and density of the regolith and bedrocks. Expected results of measurements have
been presented for a two-layer model of lunar ground, consisting of an upper
layer with the loose porous rocks (regolith), and the rocks situated more
deeply. Revealed regularities are a basis for determining the distribution of
the permittivity in subsurface layer.
