摘要
近年来,世界各航天强国加速推进星载激光雷达研制,多颗搭载对地探测激光雷达的专星发射升空,有望大幅提升卫星对地探测能力。本文主要针对近年来国外取得显著进展的星载激光测高雷达、星载大气激光雷达以及星载多普勒激光测风雷达三种典型星载对地探测激光雷达技术,介绍其当前发展现状,并总结其未来发展趋势。
In recent years,the worlds space powers have accelerated the development of spacebome LiDAR.Several dedicated satellites equipped with Earth observation LiDAR have been launched into space,which will greatly enhance the capability of satellite-based Earth observation.In this paper,three typical spacebome LiDAR for Earth observation that have made significant progress are presented,including the spacebome altimeter LiDAR,atmospheric LiDAR and Doppler wind LiDAR.Their current development status are introduced and future development trends are summarized.
