Abstract
A system and method that can determine the direction of origin within 360 degrees around an antenna array for an emitted signal with a high degree of accuracy, even when the array is installed in a corrupted or “unclean” environment. Further, the provided system and method can provide a more accurate indication of direction despite polarization of the detected signal. Finally, the provided system and method can provide accurate results from phase measurements, amplitude measurements, or both phase and amplitude measurements, from an emitted signal where a phase network can be used to tailor the amplitude and phase variations versus spatial angle to best match the receiver measurement accuracies.
