激光雷达对大气风场的光束扫描及风场反演

The Scanning and Inversion Method of Atmoshere Wind by Doppler Lidar

用激光雷达通过多普勒频移来确定激光束视线方向上的大气风场的速度矢量。通过这些测得的矢量来反演观测视场的大气风场群速的速度矢量是激光雷达的一个重要应用 ,采用 Edge技术的多普勒激光雷达是一种非常重要和有效的工具。

Utilizing lidar to abtain the wind velocity along the line of sight by Doppler shift,then inverting these vectors to real atmosphere wind group speed is a very important purpose of laser lidar.The edge technique is a new and powerful method for measuring small frequency shifts.In this article we will analyze and process these data.
