星载遥感是电磁波与环境目标相互作用散射辐射传输获取数据图像，并进而反演诠释环境目标物理特征的信息技术。随着星载遥感多任务、多频段、多极化、高分辨率等多源多模式的发展与融合，星载遥感定量精细信息的需求提出了一系列新的信息链科学问题。本文概述本实验室在近十多年里在星载遥感领域的电磁散射辐射传输理论到定量精细遥感信息链的研究，包括：矢量辐射传输与星载微波遥感数据定标与验证（CAL/VAL）、极化电磁散射与全极化多模式合成孔径雷达（SAR）成像信息、高分辨率遥感与自动目标识别（ATR）技术、月球火星等外星遥感信息获取等。

Satellite-borne remote sensing is a type of information technology that retrieves the physical characteristics of the environment/targets via scattering and radiative transfer by electromagnetic waves. A series of novel information trends for fine quantitative retrievals have emerged with the advancements of high-resolution remote sensing technology with multi-mission, multi-frequency, multi-polarization, multi-source, and multi-mode characteristics. This paper presents a general profile of the research progress during recent decades. It includes a discussion of vector radiative transfer theory of natural media and satellite-borne microwave remote sensing CAL/VAL, electromagnetic scattering theory and fully polarimetric multi-mode SAR imagery, high-resolution monitoring and ATR technology, and extraplanetary remote sensing (e.g., Moon and Mars).
