国外星载激光雷达研究进展

Research development of space-borne lidar in foreign countries

星载激光雷达可以获取全球的高精度地球探测数据,在对地观测中起到越来越重要的作用。介绍了美国和欧洲星载激光雷达的发展历程。从探测原理、探测系统和探测结果等方面分别对地球激光测高系统星载激光雷达、正交偏振云-气溶胶星载激光雷达以及大气激光多普勒测风星载激光雷达进行了详细介绍。并对3台星载激光雷达的接收望远镜的结构和材料进行了分析。可以为我国星载激光雷达的研究提供参考。

Space-borne lidar could provide us with high accurate data of global detection and play more and more importantrole in earth observation. The development of space-borne lidars in USA and Europe was introduced in brief. Working principle,detection system and detection results of geoscience laser altimeter system spaceborne lidar, cloud-aerosol lidar with orthogonalpolaritation and atmospheric laser Doppler spaceborne lidar wind measurement were summarized in detail. The construction andmaterials of the receiving telescopes of the above 3 spaceborne lidars were analyzed. The study provides some reference for theresearch of space-borne lidars in China.
