The object of study is the surface of the Moon. The subject of the research is the structural, physical, and optical properties of the surface of the Moon. The purpose of the work is to develop new, further develop and improve existing methods of remote sensing of the lunar surface based on the analysis of its photometric function and the study of the relationships between its physical/structural and optical characteristics and remote sensing of the lunar surface on this basis. The research methods are photometric and spectrometric using theoretical analysis and computer modeling for interpretation. A comparison of various expressions of phase functions is carried out and recommendations for their use for the reduction of photometric observations and solving problems of remote sensing of the lunar surface are provided. A new empirical phase χ-function is proposed. It has only 2 free parameters and allows for high-quality approximation of phase brightness curves of the lunar surface, moreover, for morphological formations of different nature, which is useful for photometric reduction of observational data. A study of the dependence of the photometric function of the Moon's surface on spatial resolution was carried out, which showed that for a scale of ~1 m/pixel, Akimov's theoretical formula best describes the brightness distribution, at least for the slopes of young symmetrical impact craters. The obtained value of the parameter ν = 1.0 differs significantly from the values of 0.34 – 0.52 determined from the analysis of ground-based observations with a resolution of 4 km. The reason for this difference needs further study. Product Description popup.authors Velykodskyi Yurii I. Velichko Sergij F Korokhin Viktor V. Opanasenko Mykola Viktorovych Surkov Yehor S.
