月基对地观测研究现状与展望

Research Status and Prospect of Moon-Based Earth Observation:A Review

在月球上布设遥感传感器能实现长期、整体、稳定的对地观测,完善现有系统的观测能力,尤其是能从地球系统外部来观测地球系统本身的演化过程,以及地球系统与外部的相互作用和影响。从科学目标、传感器技术、参数模拟和估算方法以及观测站选址4个方面详细论述了月基对地观测研究进展,围绕涉及的关键科学问题进行推进,并总结了针对传感器论证、任务设计、数据处理和信息提取提出的一系列新模型和新方法,对月基对地观测提出了一些发展建议。

The deployment of remote sensing sensors on the Moon can realize long-term,overall and stable Earth observation and improve the observation ability of the existing system.In particular,from the outside of the Earth system,the Moon-based remote sensors can observe the evolution process of the earth system and the interaction and influence between the earth system and its exterior.This paper discusses the research progress of Moon-based earth observation in detail from four aspects:scientific objectives,sensor technology,parameter simulation and estimation methods and observatory location.The key scientific problems are analyzed,and a series of new models and methods are summarized.At the end of this paper,some suggestions for the development of Moon-based Earth observation are put forward.
