ABSTRACT:
Radio direction finding equipment has an array of direction finding antennas. The antennas are connected to receivers and signals from the antennas are processed, for example with a microcomputer, to give direction information derived from the phase difference between the signals. A reference antenna is also provided and this is of greater sensitivity than the other antennas. The direction information is derived from phase differences determined between the signal from the reference antenna and the signals from the other antennas.
