Abstract:

The previously developed algorithm for estimating the circulation of aircraft wake vortices from measurements by a Stream Line pulsed coherent Doppler lidar has been improved by using the model of a pair of aircraft vortices in the algorithm that takes into account the ground effect on the spatial dynamics and evolution of the vortices. In a numerical experiment, it was shown that an improved algorithm allows obtaining a result with high accuracy, while the approach used earlier overestimates the lidar assessment of vortex circulation by about 10%.

Keywords:
