Abstract
A beacon-based approach guidance system is disclosed. A disclosed method includes digitizing at least one signal received at an antenna array of a receiver of a vehicle to digitized data streams of I and Q samples, the at least one signal received from a beacon, the at least one signal modulated with a pseudorandom code at the beacon, correlating the I and Q samples to a locally generated pseudorandom code of the receiver to recover carrier signals, and calculating, based on relative phase characteristics of the recovered carrier signals, a direction of arrival of the at least one signal from the beacon in a vehicle reference frame.
