本文件规定了单站外差连续波（CW）多普勒激光雷达技术的要求和性能测试程序，并介绍了其优点和局限性。本文件中使用的术语“多普勒激光雷达”仅适用于单站外差连续激光雷达系统，该系统通过大气气溶胶对激光的散射获取风测量值。根据标准大气条件描述了性能和限制。本文件描述了视线风速（径向风速）的测定。 注:本文件中未描述从单个视线测量值推导风矢量的过程，因为它高度特定于特定的风激光雷达配置。 ISO 28902-2:2017附录B中提供了风矢量检索的一个示例。 本文件不涉及风矢量的检索。 本文件可用于以下应用领域: -航空、机场安全、海上应用、石油平台等气象简报； -风力发电，例如现场评估、功率曲线确定； -气象站风廓线的常规测量； -空气污染扩散监测； -工业风险管理（直接数据监测或同化到微尺度流动模型）； -交换过程（温室气体排放）。 本文件可供单站连续波多普勒测风激光雷达制造商以及测试和证明其符合性的机构使用。 本文件还为用户提供了充分使用这些仪器的建议。

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.
