A novel, wide angle, high resolution Direction-Of-Arrival detector

Direction-Of-Arrival (DOA) detection is a demanding task for a wide range of applications where high accuracy, robustness, small size, and low cost are important requirements. An innovative Six-Port based DOA detector is hereby presented. Several applications benefit from the advantages of this new interferometric detection principle. A new high resolution dual Six-Port based detector is presented featuring among the advantages provided by the interferometric principle also a wide angle of detection as well as an increased dynamic range and new digital signal processing strategies.
