摘要： 激光雷达遥感可获取地物的三维结构信息，偏振遥感可实现“强光弱化与弱光强化”的信息增强，两者主被动光学遥感组合为下一代对地观测多维光学遥感新模式的研发提供一条可行的途径。事实上偏振激光雷达这一概念提出较早，但其已开展的应用主要集中在大气监测领域，研究重点侧重于激光后向散射去极化技术等方面，进一步发展到探测大气气溶胶含量及针对相关任务的信息增强技术研发等；但在其他领域，偏振激光雷达的遥感应用极其有限，而理论上偏振激光雷达具有推广到复杂地物遥感的可能性。从其两种组成模式的遥感原理角度出发探讨偏振激光雷达对地观测遥感可能实现的机理基础，并分析了其技术发展的趋势，为后续相关遥感技术的研发及其在农业、环境、海洋、空间探测等不同领域中的应用指出了可能的切入点。 关键词： 偏振激光雷达;  遥感机理;  ')" href="#">对地观测     Abstract: Light Detection and Ranging(LiDAR) Remote Sensing(RS) can map the 3D structures of objects，and polarization RS can implement information retrieval enhancement via strengthening the weak reflectance and weakening the strong reflectance that are inverse scenarios in traditional optical RS.Their combination，theoretically，can open a possible way for developing the next-generation multi-dimensional active optical RS technologies.However，the literature review suggested that the concept of polarization LiDAR was earlier proposed，while its applications mainly occurred in the field of atmospheric monitoring.The focuses were on study of laser backscatter depolarization techniques，e.g.，sensing water content in the air based on the metrics of polarization diversity so as to distinguish the structures and orientations between water vapor and ice crystal clouds in the atmosphere，and further，on investigation of aerosol content in the troposphere and improvement of the related methods.But in other fields，the applications of polarization LiDAR RS have been almost blank.Now，it is time to extend the applications of polarization LiDAR for RS of complex objects.This paper analyzed the mechanisms of the two component modules in terms of their RS principles and listed the fundamental works necessitated for comprising the polarization LiDAR RS technology.Finally，this study proposed the ranges of possibly applying polarization LiDAR RS，such as agronomy，environment，ocean and space exploration.
