Abstract
All of a plurality of analog-to-digital converters (ADCs) each operating in a first mode of operation within a spectrum of interest sample a signal received at one of a plurality of antennas, with the outputs of the ADCs processed to detect signals of interest based on a threshold. For each of the plurality of antennas, a corresponding one of the plurality of ADCs operating in a second mode of operation samples signals received at the one of the antennas such that signals received are sampled at all of the plurality of antennas, with the outputs of the ADCs processed to calculate an angle of arrival for at least one detected signal of interest using phase interferometry. Bandpass or non-uniform under-sampling may be employed to sample all of the antennas at a relatively low data rate.
