- This document specifies the requirements and performance test procedures for monostatic heterodyne continuous-wave (CW) Doppler lidar techniques and presents their advantages and limitations. The term “Doppler lidar” used in this document applies solely to monostatic heterodyne CW lidar systems retrieving wind measurements from the scattering of laser light by aerosols in the atmosphere. Performances and limits are described based on standard atmospheric conditions. This document describes the determination of the line-of-sight wind velocity (radial wind velocity). NOTE Derivation of wind vector from individual line-of-sight measurements is not described in this document since it is highly specific to a particular wind lidar configuration. One example of the retrieval of the wind vector can be found in ISO 28902-2:2017, Annex B. This document does not address the retrieval of the wind vector. This document can be used for the following application areas: — meteorological briefing for e.g. aviation, airport safety, marine applications, oil platforms; — wind power production, e.g. site assessment, power curve determination; — routine measurements of wind profiles at meteorological stations; — air pollution dispersion monitoring; — industrial risk management (direct data monitoring or by assimilation into micro-scale flow models); — exchange processes (greenhouse gas emissions). This document can be used by manufacturers of monostatic CW Doppler wind lidars as well as bodies testing and certifying their conformity. This document also provides recommendations for users to make adequate use of these instruments.

构建以激光雷达为核心的区域污染立体监测体系
风廓线雷达，也称为风廓线仪，是一种新型的测风雷达，它以晴空大气湍流对入射电磁波的散射回波为探测基础，采用多普勒雷达收发技术体制，通过依次测量1个天顶垂直波束指向和东、南、西、北4个倾斜波束指向上各个距离库的多普勒速度，在大气水平均匀的条件下，用同一高度上的5个波束指向的多普勒速度测量值联合求解出大气3维风场。我国风廓线雷达技术的发展历程可以参考文献。 ...
激光雷达的原理、应用现状及其发展
测风方面的应用多普勒测风激光雷达具有高分辨率、高精度、大探测范围、能提供晴空条件下三维风场信息的能力。多普勒测风激光雷达利用光的多普勒效应，测量激光光束在大气中传输及其回波信号的多普勒频移来反演空间风速分布。主要有相干（外差）探测和非相干（直接）探测两种方式。3. 气象方面的应用我国已经建立12个沙尘暴长期观测站，首次形成全国性的沙尘暴监测网络。...
激光雷达的七大分类有哪些？
连续激光是依靠持续亮光到待测高度，进行某个高度下数据采集。由于连续激光的工作特点，某时某刻只能采集到一个点的数据。因为风数据的不确定特性，用一点代表某个高度的风况，显然有些片面。因此有些厂家折中的办法是采取旋转360度，在这个圆边上面采集多点进行平均评估，显然这是一个虚拟平面中的多点统计数据的概念。脉冲型激光雷达脉冲激光输出的激光是不连续的，而是一闪一闪的。...
