Abstract
A system and method for a single site beacon transceiver including an omni-directional transceiver, a plurality of directional receiving antennas for receiving a signal, and a digital receiver for processing the signal to determine an azimuth to the source of the received signal. The digital receiver includes a plurality of receiver channels that are calibrated periodically and at least one processor that estimates a coarse signal azimuth for the signal by calculating an amplitude monopulse ratio for the signal using the two directional receiving antennas receiving the highest amplitude signal, and estimates a final signal azimuth for the signal using an interferometer baseline between the two directional receiving antennas or, alternately, subtracts the complex ratio of the measurements from the complex ratio of the antenna array RF model to determine the angle corresponding to the minimum of the absolute value of the difference.
