High-accuracy localization based on the dominant rays of ray-tracing over fingerprinting techniques

This paper aims to apply a novel high-accuracy localization technique in apron and stand areas in airports to increase the safety when coverage and resolution of the surveillance systems deployed is degraded. We propose a new localization method based on fingerprinting techniques using the multipath ray-profile due to effects of the ray-tracing as cost function instead of power levels measurements over the received signal strength. The precision obtained with this technique is very high, while the main contribution to the localization accuracy is provided by the dominant rays of the ray-tracing.
