Measurements of the dielectric characteristics of lunar soil samples are analyzed in the context of dielectric theory. It has been shown that the real component of the dielectric permittivity and the loss tangent of rocks greatly depend on the frequency of the interacting electromagnetic field and the soil temperature. It follows from the analysis that one should take into account diurnal variations in the lunar surface temperature when interpreting the radar-sounding results, especially for the gigahertz radio range.  相似文献

In this review, we consider all aspects of the development of heliometric and positional observations of the Moon and the investigation of its figure, rotation (physical libration), and gravitational field as well as other similar questions at the Engelhard Astronomical Observatory (EAO) and the Kazan Municipal Astronomical Observatory (KMAO) at Kazan University.  相似文献
