I.Technical Parameters

II. Working Principle

This ground-based wind LiDAR adopts laser Doppler coherent detection technology with a 1.5μm eye-safe invisible laser beam. It emits pulsed laser signals vertically into the atmosphere, receives backscattered signals generated by atmospheric aerosols, and calculates the Doppler frequency shift of the echo signal. By resolving the frequency offset value, the system accurately derives real-time vertical wind speed, wind direction and vertical velocity at any height within 30~300m. It realizes all-weather continuous vertical wind profile measurement, replacing traditional meteorological masts to acquire complete layered wind field data for wind farm monitoring and analysis.
