ABSTRACT:
Methods are known for finding the bearing of an incoming radio signal. The system disclosed, which enables accurate bearings of radio signals to be obtained rapidly, employs a rosette array of directional Beverage antennas. The antennas are rapidly scanned to find which one is receiving the largest amplitude signal; this gives an approximate bearing. This signal is then compared with the signals of two adjacent antennas in the array and the results of these comparisons provide a measure of the amount and direction that the true bearing differs from the approximate bearing.
