Abstract:
To improve lidar visualization of the wake vortex of an aircraft, we proposed using the raw data from joint measurements by three pulsed coherent Doppler lidars (PCDLs). One of these lidars uses a conical scanning beam (for background wind measurements), while the other two scan in a vertical plane perpendicular to the runway (to determine the parameters of the aircraft vortices). Using PCDLs: WPL-1, Stream Line, and WPL-2, this approach was tested in an experiment at the Tomsk airport airfield in 2025. A comparison of the aircraft vortex parameter estimates obtained from measurements by the Stream Line and WPL-2 PCDLs revealed good agreement between the visualization results.
