中文摘要：

设计了基于Fabry-Perot（FP）标准具的中高层大气（20~60 km）多普勒测风激光雷达（DWL）系统。介绍了激光雷达的多普勒测风基本原理;根据探测指标分别给出了DWL的发射机、接收机、发射接收光学和风场反演等子系统方案,重点对接收机的参数进行了详细的设计与分析;最后对全系统的信号信噪比、探测偏差进行了理论模拟。得出的结论为：当脉冲累计时间为5 min（15 000 shots）时,该系统在晚上60 km高度处的探测偏差为3.6 m/s。

英文摘要：

A Rayleigh Doppler wind lidar（DWL） system based on Fabry-Perot etalon for middle atmosphere（20-60 km） observation was designed.After the analysis of basic principle of the DWL,the subsystem blue print of DWL including transmitter,transceiver optical,receiver and wind-retrieval processing were presented.Emphasis was given on the parameters of receiver for deep analysis and study.The signal noise ratio（SNR） of whole system and line-of-sight（LOS） wind speed error were simulated.And the result show that when typical integration time is 5 mins（15 000 shots） and clear air lidar wind profiles extend to altitudes of 60 km with 1 km vertical resolution,the wind speed error ranges up to 3.6 m/s at nighttime.
