ABSTRACT:
An antenna configuration system for determining the bearing angle of a radio frequency signal includes a plurality of loop antennas and at least one sense antenna. Through the utilization of combining networks with the loop antennas, in-phase and out-of-phase output signals are summed with the signal from the one sense antenna. The summed signal is sent to an adaptive processing system to allow for the determination the bearing angle of the radio frequency signal.
