Abstract. A comparative analysis of the soil's dielectric spectra with differ salt content was carried out. Laboratory measurements of dielectric constant were carried out for soil samples selected in the basin of Lake Ebeity and the southwestern part of the Omsk region. A general description of the dielectric spectra and radiophysical characteristics associated with them is given. These dependencies can be used in assessing the radiophysical characteristics of the underlying surface when solving applied problems of radiation and propagation of radio waves.

Key words: complex dielectric permittivity, underlying surface.

Financing: the work was carried out according to the state task of the Omsk Scientific Center SB RAS (project registration number 122011200349-3).
