介绍了一种基于分子双面技术的多普勒激光雷达系统。该系统安装在一辆改装的货车上，以便在现场作业中部署。激光雷达使用355纳米的三倍Nd:YAG激光器，一个45厘米口径的望远镜，和一个匹配的方位角-过仰角扫描仪，以允许全天空访问。在垂直分辨率为178米的范围内，测量了1.8至35公里的有效大气风廓线。水平风速的距离相关均方根偏差为0.4 ~ 6 m/s。测得的风速和风向与同一地点同时测得的雷达探空风值吻合较好。(C) 2000美国光学学会OCIS代码：010.3640,120.2230,010.7030,120.0280。
A Doppler lidar system based on the molecular double-edge technique is described. The system is mounted in a modified van to permit deployment in field operations. The lidar operates with a tripled Nd:YAG laser at 355 nm, a 45-cm-aperture telescope, and a matching azimuth-over-elevation scanner to permit full sky access. Validated atmospheric wind profiles were measured from 1.8 to 35 km with a 178-m vertical resolution. The range-dependent rms deviation of the horizontal wind speed is 0.4-6 m/s. The measured wind speed and direction are in good agreement with the rawinsonde wind measurements made simultaneously from the same location.
