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）. 散射辐射传输 微波遥感 SAR成像 目标识别 遥感信息链 scattering and radiative transfer microwave remote sensing SAR imagery target recognition information train of remote sensing TP7 2021-06-09 5 20
