Abstract: 
Analysis of the state of lunar explorations shows that the global multifrequency survey of the Moon at the radio wavelength range is a promising task for a lunar polar spacecraft. The survey will allow mapping the characteristics of the lunar subsurface layers and, in particular, estimation of the thickness of the lunar regolith. Actuality of such a task has grown after the "Clementine" mission (a brief review of the mission findings is presented in the paper). To illustrate the radar spacecraft experiment, the regolith thickness map of the lunar nearside derived from radar and optical Earth-based observations is presented.
Keywords: Moon, radar spacecraft, regolith thicknes
