Abstract : Design, development, and testing of a 4-element 4-channel adaptive array for interference rejection and of an angle of arrival estimation device for use with the Phase III remote sensor communications system are described. The adaptive array provides simultaneous monitoring of four selected sensor channels within the 162-174 MHz sensor band while nulling up to three interfering signals from spatial directions to within 2.5 degrees of the desired signals. The angle of arrival estimation system determines the angle of arrival estimation system determines the directions of multiple incident signals simultaneously. (Modified author abstract)
