摘要
激光雷达的技术优势使其成为继可见光、红外和微波天基遥感仪器之后对地精确观测的重要技术手段之一。本文简要介绍天基遥感任务地球观测激光雷达中后向散射激光雷达、激光高度计、多普勒激光雷达、差分吸收激光雷达（DIAL）的发展计划和技术体制特点，以及NASA为了提高天基激光雷达可靠性而实施的激光风险降低计划（LRRP）的进展，分析天基激光雷达的关键技术。
Owing to technology advantages over CCD, infrared and microwave based space -borne remote sensing systems, space -borne lidar has become an effective means for accurate earth observation. Some development programs and technical routes of space -based remote sensing missions using lidars, such as baekscatter lidar, laser altimeter, Doppler and DIAL lidar, and progress of NASA＇s LRRP program for improving the reliability of space lidars are summarized in this paper. Some key techniques of space - borne lidars are also analyzed.
