月壤厚度的研究方法与进展

月壤厚度的研究对未来月球探测、登月与月球资源开发均具有十分重要的意义。它是恢复月球起源和演化历史的重要参数,也是估算月球3He资源量的必要前提。本文将月壤厚度的研究方法归纳为直接和间接两类,直接方法主要是利用月震数据对月壤厚度进行推算,间接方法包括基于撞击坑形态、分布以及地基雷达遥感数据估算月壤厚度两种。随着定量微波遥感的发展,结合我国嫦娥探月工程的实施,利用高分辨率被动微波遥感亮温反演月壤厚度为月壤厚度的研究指出一个新的方向。

METHODS AND ADVANCES IN RESEARCH ON LUNAR SOIL THICKNESS

Research on lunar soil thickness is very important in lunar exploration,human lunar landing and lunar resource exploitation in the future.It is an important parameter in the study of the origin and evolution of the Moon,and it is the prerequisite for estimation of the quantity of 3He on the Moon.The research methods of lunar soil thickness can be classified as direct and indirect methods.The direct methods mainly used to estimate lunar soil thickness in term of the moonquake data.The indirect method is used to estimate lunar soil thickness based on the morphology and distribution of lunar craters,or based on the data from Earth-base radar remote sensing.With the development of microwave remote sensing and the implementation of Chang'e project in China,the inversion of lunar soil thickness using the brightness temperature derived from high-resolution passive microwave remote sensing is a new orientation in research on lunar soil thickness.
