Doppler Lidar Could Aid Weather Forecasting, Aircraft Safety

Facebook X LinkedIn Email
A dual-frequency direct detection Doppler lidar system could offer a simplified yet robust way to accurately measure wind speed. The detailed, real-time wind measurements provided by the system could help scientists better understand how hurricanes form and provide information that meteorologists could use to pinpoint landfall earlier. Mingjia Shangguan and Haiyun Xia from the University of Science and Technology of China were part of a research team who developed a new Doppler lidar system for accurately measuring the wind. It features a greatly simplified optical setup that makes it...Read full article

    lidar
    Lidar, short for light detection and ranging, is a remote sensing technology that uses laser light to measure distances and generate precise, three-dimensional information about the shape and characteristics of objects and surfaces. Lidar systems typically consist of a laser scanner, a GPS receiver, and an inertial measurement unit (IMU), all integrated into a single system. Here is how lidar works: Laser emission: A laser emits laser pulses, often in the form of rapid and repetitive laser...
    remote sensing
    Remote sensing is a method of data collection and observation where information about objects, areas, or phenomena on Earth's surface is gathered from a distance, typically using sensors onboard satellites, aircraft, drones, or other platforms. This technique enables the monitoring and analysis of Earth's surface and atmosphere without direct physical contact. Remote sensing systems capture electromagnetic radiation (such as visible light, infrared, microwave, or radio waves) reflected or...
