Abstract In the background of phase ambiguity in using phase interferometer to estimate the direction of arrival, a new method is proposed for estimation direction of arrival by using interferometer array with the algorithm named as multi-pare unwrap ambiguity. The possibility of correction is analyzed. The conclusion is verified by simulation result.
