Abstract. Microwave radiometers have proven to be useful tools for studying the thermal regime of the atmosphere and the Earth's surface. Similar devices were recommended for inclusion in the composition of scientific radio equipment designed to study other bodies of the solar system, in particular the moon. The degree of understanding of the physical foundations of the experiments and the accuracy of their theoretical description is the coincidence of the results of measurements and numerical simulation of radio brightness temperature. The paper discusses the mechanism for calculating this value, deriving a recurrent formula convenient for calculating the radio brightness temperature from the Moon's soil. The algorithm is built for flat-layered soil. The depth distribution profile of physical temperature and complex permittivity for this problem are a priori information.

Key words: microwave radiometry, radio brightness temperature, dielectric permittivity, soil, the Moon.

Financing: The work was carried out within the framework of the State Assignment of the Kotelnikov’s Institute of Radio Engineering and Electronics of Russian Academy of Sciences № 075-01133-22-00.
