Interferometric angle-of-arrival (AOA) ambiguities due to local multipath reflections are resolved by measuring the received phase differences of one or more pairs of antenna elements of the interferometer array, constructing hypotheses from unwrapped phase pairs that correspond to potential AOA solutions, and selecting the hypothesis that most likely represents the true AOA of the signal emitter based on processed unwrapped data that has been corrected through the application of a priori calibration terms selected on the bases of the candidate hypotheses.
