Measurements of atmospheric wind speeds at distances up to 60 m using a dual beam laser Doppler velocimeter with digital autocorrelation analysis, an unfocused argon ion laser (0.10-0.35 W) at 5145 A, and a 20-cm collecting telescope are reported. Criteria affecting the field performance of this system and an expression giving the power and range dependence of the data accumulation rate are presented. Major improvement of the system's performance can be made by focusing the laser beams and properly restricting the field of the collecting telescope. The potential of this technique for remote wind measurement at ranges of several hundred meters is discussed.
报道了使用具有数字自相关分析功能的双光束激光多普勒测速仪、波长为5145埃的非聚焦氩离子激光器（功率0.10 - 0.35瓦）以及一台20厘米收集望远镜，在距离达60米处测量大气风速的情况。给出了影响该系统现场性能的标准以及一个表示数据积累速率与功率和量程依赖关系的表达式。通过聚焦激光束和适当限制收集望远镜的视场，可以对系统性能进行重大改进。讨论了该技术在几百米量程进行远程风速测量的潜力。
