Timely advance warning of turbulence ahead of an aircraft may allow the pilot to take steps to minimize any damage or to avoid the hazard entirely. To enhance flight safety, the National Aerospace Laboratory of Japan is developing a practical 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 Doppler LIDAR with a 1.5-micron laser. 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. The prototype has been installed on an aircraft and a flight demonstration will be carried out in September 2002. This paper describes the development of a prototype LIDAR device. 資料番号: AA0045946004 レポート番号: NAL SP-55 航空宇宙技術研究所 National Aerospace Laboratory (NAL) 2002-12 jpn conference paper https://jaxa.repo.nii.ac.jp/records/38184 1347-457X AN10097345 航空宇宙技術研究所特別資料: 平成14年度航空安全・環境適合技術研究研究交流会と研究報告会講演論文集 Special Publication of National Aerospace Laboratory: Proceedings of the Information Exchange Meeting and the Research Meeting on Aviation Safety and Environmental Compatibility Technology Research FY2001 55 75 78 https://jaxa.repo.nii.ac.jp/record/38184/files/nalsp0055204.pdf application/pdf 99.7 kB 2020-01-24
