Airborne Wind Lidar
The remote sensing airborne wind Lidar provides a new solution for the rapid monitoring of mountain wind field. Conventional hand-held monitoring equipment can only monitor single point ground wind, and cannot perceive the wind field above the forest.
Description
Production Introduction
Description
Traditional monitoring equipment can only monitor single-point ground wind, but can't sense the wind field over the forest. This Airborne Wind Lidar uses AWL technology, using small flying drones to capture airflow at different heights, which provides a new solution for rapid monitoring of mountain wind field. This radar can quickly and flexibly obtain the information of atmospheric wind field vertically distributed in the route area and the target area, and has the advantages of high spatial resolution, high temporal resolution and high measurement accuracy.
Features
1. Compact structure: Airborne Wind Lidar adopts a small structure, which has the characteristics of light weight and low power consumption. It can be carried on unmanned aerial vehicles and other platforms for real-time monitoring, and quickly obtain wind field information in forest areas.
2. Stable operation: The radar adopts an attitude correction algorithm customized for UAV platform, which can calibrate the height and deflection angle of UAV in real time during operation, and keep driving at a constant speed to make it run smoothly and have strong anti-vibration ability.
3. Various monitoring methods: It adopts coherent detection and direct detection. Its coherent detection depends on the Michaelis backscattering measurement of aerosol or cloud particles, which can obtain the reflection spectrum of aerosol or cloud particles with a diameter of tens of microns to about 1 mm. However, the direct detection uses the Mie and Rayleigh backscattering of aerosols and smaller atmospheric molecules to measure the wind, which can measure the three-dimensional distribution of wind speed and direction.
4. High accuracy: The radar adopts conical gaze mode, and can observe from the lowest point to 8 or more different directions. This makes it possible to distribute the height of wind measurement in the atmospheric column more accurately, and effectively avoid the cross-interference problem between the layers of the atmosphere.
