Leice - Scanning LIDAR | Wind3D 6000
Based on the principle of optical coherence Doppler frequency shift detection, the Wind3D 6000 the 3D scanning wind lidar can realize the fine detection of three-dimensional wind field in atmospheric boundary layer.
With high pointing precision optical scanning rotating mirror, the 3D scanning detection function can be realized, and the maximum detection radius can reach 6 km.
Characteristics
SCANNING MODES
The scanning system of Wind3D 6000 scanning coherent Doppler lidar has strong programmability. The measurement plan and Lidar scanning mode configuration can be developed as per scope of the measurement and site conditions.
1. DBS ( Doppler Beam Swinging) wind profile scanning
Wind profile is the change curve of horizontal wind speed in the atmosphere with altitude. Wind3D 6000 can continuously collect the Wind profile information directly above equipment, by measuring Radial wind speed of the five directions of east, south, west, north and vertical in turn, to calculate wind speed and wind direction profile data.
2. PPI ( Plan Position Indicator) scanning
Wind3D 6000 scans the radial wind speed over a large area with a fixed pitch angle and varying azimuth angle. This scanning method can clearly see the change of radial velocity information on the scanning surface, which is suitable for retrieving horizontal wind field at relatively flat terrain, or fine measurement the amount of wake, wind shear, etc.
3. RHI ( Range Height Indicator) scanning
Wind3D 6000 scans at a fixed azimuth and changes the pitch angle, scanning one or more vertical plane slices from top to bottom or bottom to top. This scanning method is suitable for observing changes in wind speed on the vertical plane.
4. Spot Scanning
Wind3D 6000 can collect radial wind speeds in these directions in sequence according to the configured multiple azimuth and pitch angles. This method is generally used in conjunction with some customized inversion algorithms, or in order to improve the time resolution of PPI / RHI and speed up the acquisition speed of a single PPI / RHI. The collected data generally needs to be processed after post-processing.
5. Virtual wind tower scanning
Wind3D 6000 uses PPI scanning to scan a range at the target location (generally requires an azimuth greater than 60 degrees), which can reverse the wind speed and direction at that location. This method is suitable for measuring some places where it is inconvenient to place the radar under the measuring point, or some points with a lower height that cannot be directly measured by the wind profile.
