ABSTRACT:
Precise azimuth and elevation angles of arrival of a signal are determined using a rotating interferometer wheel rotatable about an axis parallel to the boresight of the interferometer. The angles of arrival are determined based on the measured phase differences of signals received by the interferometer, corresponding cone angles and the assignment of azimuth and elevation values to the group of conic lines which are nearest each other.
