直接探测多普勒测风激光雷达

摘要

Basic theory of direct etalon and the fringe technique Doppler shift can be got by the detection Doppler wind lidar is introduced, and the edge technique based on F - P based on Fizeau interferometer are analyzed and simulated. It is shown that the two techniques, and the wind speed is retrieved by Doppler effect.%介绍了直接探测多普勒测风激光雷达的基本原理，并对基于F—P标准具的边缘技术和基于Fizeau干涉仪的条纹技术进行了分析和仿真研究。结果表明：采用两种技术均可获得多普勒频移，并通过反演得到风速。
