Multiple Source Angle of Arrival Estimation Through Phase Interferometry

IEEE Transactions on Circuits and Systems - II - Express Briefs, 2022
The evaluation of the Angle of Arrival (AoA) of a received signal is a basic tool for many RF location systems. This brief introduces a new technique for estimating the AoA via a phase interferometric approach when multiple sources are present.
