“…The calculations were performed under the assumption that there is no surface roughness and volume scattering but only taking into account the attenuation in the medium. The results of model calculations of scattering from a spherical object, a dielectric disk, a metal plate in a soil are given in [9][10][11][12][13]15]. In this case, the problem of finding reflection from a dielectric object was solved in a rigorous electro-dynamic formulation.…”

A method for constructing a deep profile of the "effective" moisture of the upper layer of the earth's surface is proposed. Ground experiments were conducted to determine the characteristics of the " diversity " of moisture and soil cover heterogeneities. The special attention was focused to using of ground penetrating radar for investigations of upper ground layer heterogeneities. The ground experiments were dictated by the need to justify the proposed algorithm for deep sounding of agricultural fields in the winter period at a low temperature with the help a synthetic antenna radar. Keywords: synthetic antenna radar, ground penetrating radar, subsurface sensing, deep profile of the "effective" moisture, the "variety" of soil cover.
