Zusammenfassung:The present disclosure is a system comprising at least three electronically steered antennas arranged so that there is a baseline difference of a predetermined amount of wavelength between the centers of the antennas, typically configured as an obtuse or scalene triangle, where the distance between each antenna on an array is selected to provide the required accuracy and precision, the array having a timing circuit to ensure that the beam of each antenna is steered to the same azimuthal and elevation coordinates in space simultaneously. This enables the three electronically steered antennas to operate as an interferometer to determine a bearing to a target to ultimately determine the location thereof. The electronically steered antennas enable the system to be mounted on a platform in a small package that was previously difficult for traditional interferometers.
