Abstract:
A method for determining an angle-of-arrival for a detected signal. The method includes the steps of receiving the signal at a first antenna, receiving the signal at a second antenna, generating a plurality of spectral lines based on a complex multiplication of a complex conjugation of the signal received at the first antenna and the signal received at the second antenna, generating a delta phase difference for pairs of the spectral lines using frequency differences, and generating an angle-of-arrival for the detected signal based on an average of the delta phase difference.
