1.5 μm all fiber pulsed lidar for wake vortex monitoring

摘要

This paper illustrates the good results obtained with a pulsed lidar based on MOPFA 1.5um laser, for detection and monitoring of wake vortices on airport fields. Operational ranges larger than 400m have been demonstrated, with a 60μJ, 15kHz, 250ns pulse fiber doped Er laser. Wake profiles, positions and circulations can be derived from recorded data. During the next months, the system will be automated and miniaturized by Leosphere for a future deployment on airports. Increasing the power of fiber lasers remains a topic of interest at Onera/Dota, and longer range wind lidars (800m) are expected soon.
