Abstract
A method for finding a direction associated with a radiated electromagnetic wave, the method including the steps of: detecting the radiated electromagnetic wave; measuring at least one gain difference and at least one phase difference associated with the detected electromagnetic wave; estimating an elevational angle and an azimuthal angle associated with the detected electromagnetic wave using the at least one measured gain difference; determining a plurality of possible elevational and azimuthal angles associated with the detected electromagnetic wave using the at least one measured phase difference; and, respectively selecting one of the plurality of possible elevational and one of the plurality of possible azimuthal angles as elevational and azimuthal angles associated with the detected electromagnetic wave using the estimated elevational and azimuthal angles.
