Development of a high power Doppler Wind Lidar for measuring wind and EDR along aircraft approaches

摘要

Air flows in the troposphere have a major impact on air traffic safety and operations. In the framework of the European UFO project LEOSPHERE and ONERA have developed a new high powered scanning Doppler LIDAR using an innovative powerful Erbium doped fiber laser amplifier. The performances of this prototype have been evaluated through a campaign in 2014 performed at Toulouse airport, France. In addition, specific algorithms have been developed for retrieving wind and EDR quantities along aircraft approaches and in 3D around airport. The wind and EDR measurements have been then compared to reference sensors in order to assess their accuracy.
