Research and development of a wind turbulence prediction system - trial of a coherent Doppler LIDAR

摘要

To enhance flight safety, the National Aerospace Laboratory of Japan is developing a onboard remote wind measurement sensor based on a LIDAR (Light Detection and Ranging) that will be able to detect windshear, downbursts and clear air turbulence. A breadboard prototype sensor has been developed that uses a coherent D9ppler LIDAR. The target measurement range of the prototype is 1 km in flight, and it has measured wind at a distance of 2.25 km in a ground trial. This paper describes the results of a feasibility study into onboard wind measurement remote sensors and the development of a prototype LIDAR device.
