Wind Measuring Lidar

The Wind Measuring Lidar is a photoelectric instrument which uses Doppler effect of laser back scattering of aerosol particles drafting with wind to measure wind field distribution. Under servo control, the laser scans aerosol particles in atmosphere for three-dimensional wind field. The sequence of radial velocity in laser sight direction is identified via Doppler shift generated by aerosol movement. Using sequence,the wind field distribution can be obtained by retrieval. The range of measurement is up to 3km. The lidar is featured by good identifying ability, high accuracy, good interference resistance, small blind zone, quick reaction, simple installation and easy maintenance.

Description

Features

Coherent Doppler lidar detection principle - measures wind velocity directly from the Doppler shift of laser back scatter off atmospheric aerosols, providing fine-resolution, line-of-sight wind measurement independent of radio frequency spectrum allocation

High spatial resolution profiling - laser beam acclimation enables fine vertical resolution across the low-altitude detection envelope, resolving wind shear layers, turbulence structures, and low-level jet stream boundaries with greater vertical detail than microwave pro filers at equivalent altitudes

Automated wind hazard identification - onboard wind data quality control and intelligent identification algorithms continuously analyze the Doppler wind profile to detect and output wind shear, low-level jet stream, and wake turbulence features in real time

Eye-safe laser operation - designed to meet eye-safety standards for deployment in populated environments including airport terminals, urban monitoring stations, and public infrastructure sites

Mobile station rapid self-deployment - the mobile configuration integrates automatic north-finding, automatic leveling, and motorized antenna erection and stowage for rapid setup and pack-down at unprepared field sites

Application Fields

It can be used in airport navigation, weather forecast, offshore meteorological research,environmental impact assessment, wind farm siting and meteorological support for major activities.

Why Choose Our Wind Measuring Radar

This coherent Doppler lidar works purely with optical signals, free from spectrum approval and RF disturbance even amid dense electromagnetic signals at airports and city areas. Its laser beam delivers sharper vertical details of wind shear and turbulence close to ground, ideal for flight safety checks and wind farm fine positioning. It spots hidden aircraft wake turbulence that microwave radar fails to capture, expanding safety monitoring coverage. Laser remote sensing needs no on-site facilities, easily measuring winds over sea platforms and rugged mountains. The eye-safe design supports safe setup in crowded public zones. Built-in automatic calibration lets the mobile unit get fully operational quickly anywhere reachable.
