利用多普勒测风激光雷达(DWL)进行实地风场探测，对探测数据进行深入分析。介绍了基于三通道法布里珀罗(FP)标准具的多普勒频率检测等基本原理，给出了DWL结构组成和系统参数；并分别给出了该DWL与风廓线雷达(WPR)低空对比探测数据、与气球探空仪高空对比探测数据，结果表明，低空数据的风速偏差在0.1~1.2 m/s，风向偏差在1°~9°之间，高空数据的风速偏差在0.1~2 m/s之间，风向偏差在1°~12°之间，表现出良好的一致性；对DWL数据精度进行分析，得出光束入射角、发散角、信噪比和探测器是影响精度主要因素的结论，从标准具透射率扫描拟合曲线入手，计算得出该型DWL实际探测偏差值高出理论值2.07%。

Doppler wind lidar (DWL) is the tool with high accuracy and high temporal and spatial resolution. Wind has been detected with DWL and its data are analyzed. The fundamental of transmission of laser in atmosphere based on aerosol and molecule scattered and principle of Rayleigh Doppler wind lidar discriminating frequency based on Fabry-Perot (FP) etalon, the framework and parameters of the DWL are presented. The results from DWL are compared with wind profile radar (Airdal 6000) and Balloon, in the lower atmosphere its maximum wind speed error is 1.2 m/s and direction error is 9°, its minimum wind speed error is 0.1 m/s, while in the higher atmosphere its maximum wind speed error is 2 m/s and direction error is 12°, its minimum wind speed error is also 0.1 m/s. Experimental results indicate good agreement. The precision of the DWL is analyzed, and the incidence angle, emanative angle, signal noise ratio and parameters of detector are the master factors affecting the precision. From the transmission curve of FP etalon, the actual error of DWL is calculated and it is 2.07% higher than the simulated value.
