| Outline of Final Research Achievements |
Lunar surface permittivity is an important parameter for understanding the Moon and has been observed by many radar experiments from spacecraft. In these observations, frequencies of radio transmissions are generally high because of instrumental limitations. One of the interesting topics about the lunar surface permittivity is its frequency response in lower bands which is related to the moisture content. The Japanese lunar orbiter Kaguya carried out radar observations of the lunar subsurface structures and also passive observations of natural waves in super low frequency. In this study, we developed an estimation method of lunar surface permittivity for low frequencies by using the natural wave data of Kaguya. We also created a global map of lunar surface permittivity for high frequencies from the radar observations.
