Product Description:
Molas 3D: Advanced 3D Scanning Doppler Wind Lidar
The Molas 3D is a cutting-edge three-dimensional scanning Doppler wind measurement lidar, designed on the fundamental principle of pulsed laser coherent Doppler frequency shift. By emitting pulsed laser beams and detecting the frequency changes in backscattered signals from atmospheric aerosols, this system accurately calculates the line-of-sight wind speed and direction at multiple spatial points. This capability enables the reconstruction of high-resolution, three-dimensional wind fields.
This lidar system offers a diverse range of scanning modes to meet various measurement needs:
-
PPI (Plan Position Indicator):
Enables horizontal sector or full 360° scanning, which is perfect for mapping wind fields across extensive areas.
-
RHI (Range Height Indicator):
Facilitates vertical elevation scanning, ideal for capturing vertical wind profiles and boundary layer structures.
-
DBS (Doppler Beam Swinging):
Employs multi-beam fixed-direction scanning to accurately retrieve horizontal wind vectors and vertical velocity components.
-
Program Scan:
Allows user-defined custom scanning trajectories, offering maximum flexibility tailored for specialized research projects.
The Molas 3D boasts impressive measurement capabilities, featuring a maximum acquisition range of 15 kilometers and an effective sight detection range of 10 kilometers at an altitude of 600 meters. Its vertical measurement extends up to 4 kilometers, with configurable distance resolutions of 15, 30, 75, or 120 meters, and support for up to 300 measurement layers. Wind speed detection spans from -75 m/s to +75 m/s, providing a high accuracy of 0.1 m/s. The scanning head can rotate 360° horizontally and tilt vertically between -10° and 190°, with a pointing precision of ±0.005°, ensuring consistent and reliable data collection.
Designed for a broad spectrum of challenging applications, the Molas 3D excels in:
-
