ABSTRACT:
In one embodiment, a system includes at least two detector devices, each detector device for independently detecting a phase event of a composite signal comprising one or more traveling wave signals to provide phase event information. The system further includes a processor configured to receive the phase event information from each detector device and to estimate a direction of arrival of at least one of the traveling wave signals based on the phase event information.
