Phased array antenna system having prioritized beam command and data transfer and related methods

摘要

A phased array antenna system may include a substrate and a plurality of phased array antenna elements carried thereby, and a plurality of subarray controllers for controlling respective groups of phased array antenna elements. The phased array antenna system may further include a central controller for generating priority beam control commands and non-priority beam control commands for the subarray controllers, and a communications bus connecting the subarray controllers to the central controller. The central controller may send the priority beam control commands to the subarray controllers via the communications bus on a substantially real time basis with time gaps therebetween. Further, the central controller may also send the non-priority beam control commands to the subarray controllers via the communications bus during the time gaps.
