  • Radio direction finding systems
    Patent number: 4328499
    Abstract: A radio direction finding system in which the angle of arrival of radio signals incident on a group of antenna elements is determined from the relative phase or phases of the radio signals incident upon two or more of said antenna elements. One of said elements is connected to a first radio receiver, while the other elements of the group are connected in turn to a second radio receiver, successive values of relative phase between signals received by the two receivers being utlized to derive a value for the angle of arrival of a radio signal relative to the antenna elements.
