Abstract
A method is disclosed for determining an angle of arrival of an incident plane wave received by an antenna array. The method includes receiving signals from a plurality of antenna receiving channels, determining a set of possible angles of arrival of the incident plane wave based on the signals received at the plurality of receiving channels, measuring a pulse delay of the incident plane wave between the signals received at the plurality of receiving channels, and calculating the angle of arrival of the incident plane wave based on the set of possible angles of arrival and the measured pulse delay.
