The wake vortex generated by the wing tip of the aircraft and the low-altitude wind shear at the airport are meteorological factors affecting the flight safety of the aircraft. In particular, the final approach and initial take-off are the most dangerous

The high spatial-temporal resolution lidar can scan and invert the position, characteristics and evolution of the aircraft wake, and improve the airport operating efficiency.

Lidar technology is one of the best means of detecting wind shear to ensure the takeoff and landing safety of the aircraft.
