摘要： 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.

摘要： An antenna element suited for direction finding (DF) with omni-directional radiation patterns utilizing a pair of chevron slots fed using a ridged waveguide magic tee (magic-t) and connected microstrip probes. The provided antenna element provides improved performance, power handling, and improved bandwidth compared to current monocone and/or slot antenna elements. The antenna element may be further realized utilizing additive manufacturing processes in combination with standard metal and polymer production techniques.
