Abstract

Simulated signatures of aircraft wakes as detected by a scanning coherent short wavelength lidar are presented and characterized for a number of candidate surveillance scenarios. Ground based and airborne scanning configurations that emulate candidate operational detection and warning systems are compared for spatial coverage and detection capability as a function of system design parameters and atmospheric conditions. Examples of trailing geometries characteristic of onboard wake detection and warning systems are presented. The dependence of predicted detection capability on hydrodynamic parameters, such as vortex circulation, axial motion in the wake vortices, and ambient turbulence is discussed. Simulated wake signatures are compared to observations for wakes observed at Denver's Stapleton International Airport in 1993.
