Abstract
A method for detecting a beacon signal using an above-ground tracker. The tracker comprises an antenna assembly comprising a plurality of antennas. Each antenna is oriented in a different direction. During operation, if the beacon signal is interrupted due to a local noise source, transmission of the beacon signal is stopped. The tracker then detects radiation from the local noise source and the processor determines a direction from which peak ambient noise arrives at the tracker. The beacon signal is then resumed. A processor included in the tracker excludes any signals generated by the antenna assembly that are representative of radiation that arrived at the tracker from the same direction the peak ambient noise arrived at the tracker. The tracker then detects the beacon signal using the non-excluded signals.
