Abstract In the background of phase ambiguity in using phase interferometer to estimate the direction of arrival, a new algorithm is proposed for estimation Direction Of Arrival (DOA) using phase interferometer array with cosine function. The condition on the uniqueness of the estimation direction of arrival is obtained, which is looser than the one of the other algorithms. Simulation results under different condition show that as far as the uniqueness is satisfied, this new algorithm is available for the estimation direction of arrival.
