Abstract

A system determines the azimuth of a source of an interfering signal. The system steers a first null beam in the direction of transmitting device and also steers a second null beam in the direction of the interfering source producing and providing the interfering signal. The system measures an angle to the first null beam. The system also measures an angle to the second null beam. The system calculates the azimuth of the antenna based on the measured angle to the first null beam and a known absolute bearing of the transmitting device. The system calculates the azimuth of the interfering source based on the measured angle to the second null beam and the previously calculated azimuth of the antenna.
