Product Details

S4000 3D Scanning Doppler Wind LIDAR


S4000 Doppler Wind Lidar with the abilityof 3D wind fieldmeasurements in atmospheric boundary layer and lower tropospheric is designedfor applications in various fields such as wind power, aviation weather andclimate, air quality and so on. It is a coherent Doppler lidar with highefficiency and sensitivity. The compact all-fiber configuration

turns the lidar into a portable autonomous system with no electromagnetic


S4000 3-D wind lidar works at eye-safewavelength in near infrared spectrum (1.4um-2.2um), probes the wind field from the ground to 4000m at very high temporal resolution (second level) and spatial resolution(30 m) and accuracy (≤0.1 M / s). It compensates the disadvantages of wind profiler radarin detection capacities, and can continuously obtain the 3-D wind field parameters within the scope of atmospheric boundary layer.

This 3-D Lidar will boost the offshore wind power and complex site wind farm markets

with advancedtechnology at lower cost.


Eye safety, ultra-portable, low powerconsumption, quick launch, easy operation

Unattended and continuous operations inharsh mountainous regions, and can turn on/off automatically according to theweather conditions.  

Measure max. altitude 4000m at variousscanning ways like DBS、VAD、PPI、RHI etc.

Can probe windspeed, direction, shear and air turbulence instantaneously with high speed datasampling rate
