Abstract
A surface acoustic wave interferometer direction finding and frequency idification method and apparatus is disclosed. The invention utilizes a plurality of dispersive delay lines in order to represent a multiplicity of signals, having different frequencies and angles of arrival at a plurality of antennae, by a train of pulses which retain phase information. Analysis of the interpulse spacing among the pulses in this pulse train, which represents the difference in frequency among the multiplicity of signals arriving at the antennae of the invention, and a pulse comparison of the signals at each of the antennas, allows selective correlation of signal with angle of arrival.
