APPARATUS AND METHOD FOR ESTIMATING ANGLE OF ARRIVAL IN REAL TIME - An apparatus for estimating an angle of arrival includes: a plurality of direction synthesizing units shifting the phase of each of a plurality of signals received by an array antenna such that the angle of arrival of each of the received signals is changed by a predetermined change angle; and an estimation unit estimating the angle of arrival of the received signal by using radiation gains of two phase-shifted signals among the signals phase-shifted by the plurality of direction synthesizing units.
