摘　　要：地球系统的观测正从看清地球的样貌深入拓展到探测、分析、认知地球圈层的内在。基于天基、空基、陆基等观测平台,利用电磁、微波、激光和重力等穿透性、多维度、高密度的新型透视遥感探测前沿技术,“透视地球”对大气圈、水圈、生物圈、岩石圈等地球空间物理要素、内部结构及其演变过程进行精细、综合探测,获取地球各圈层更“精确”、更“深层”的信息,成为新一代对地观测技术发展的积极探索和重要方向。本文阐述了透视地球的概念和内涵,依据“透视方法—载荷集成—探测试验—参数反演—效能验证”的设计思路,提出透视地球原型系统的构建方案。通过多谱段耦合、多物理量融合,提升空基跨平台协同探测能力,改进遥感观测的信息维度、尺度和密度,以透视视角拓展人类对各圈层的认知边界,推动地球系统重大科学问题的突破,提升人类进行资源开发与利用、预测应对极端天气事件及环境变化的能力。Earth is a complex giant system.The spheres of earth,such as the Atmosphere,Hydrosphere,Biosphere,and Lithosphere,are interconnected and interact on each other as subsystems of the giant system.However,achieving a comprehensive and profound understanding of the spatial-temporal processes and interaction mechanisms within Earth system remains an imposing scientific endeavor.One significant obstacle is the limited availability of fine and interior data of spheres that can support groundbreaking researches on critical Earth system science topics and applications of remote sensing observation to the earth.Thus,there is an urgent need for systematic,multi-dimensional,and multi-scale observation information of the interior of the earth’s spheres to effectively address these concerns.Utilizing multiple observing means—including satellites,aircraft,and ground-based systems,along with advanced remote sensing detecting technologies that cover a spectrum from electromagnetic to microwave,laser,and gravity,the physical elements,internal structure,and evolution processes of the atmosphere,hydrosphere,biosphere,and lithosphere can be finely and comprehensively measured.Integration on diverse observing means will greatly enhance the ability to acquire highly accurate and deeply detailed insights into the earth and its subsystems.This paper proposed the concept of Transparent Earth-Observing(TEO)and its composition,which refers to the integration of new transparent-detecting model and advanced remote sensing technologies to acquire comprehensive,dynamic,and multi-dimensional interior information of Earth spheres.Transparent Earth-Observing helps to overcome the limitations of traditional Earth observation methods that primarily focus on the Earth’s surface,facilitating multi-dimensional,penetrative,high-resolution sensing of internal structures and process variation within the atmosphere,forests,oceans,and solid Earth.Transparent Earth-Observing,to a certain extent,symbolizes a new era in earth observation.This paper also
