A distributed control system for an active array antenna system is disclosed. In an exemplary embodiment, the array system employs many transmit/receive (T/R) modules each with an associated radiator element, a phase shifter element and a set of RF switch elements to set the module to transmit or receive modes. The array system is arranged to generate a transmit or receive array beam. The distributed control system in an exemplary embodiment includes an array processor for controlling the array, the processor configured to generate command signals to set the T/R module elements to transmit or receive mode and to steer the array beam to a desired direction. The command signals to steer the array beam include phase slopes common to all T/R modules in a given array or subarray. Each T/R module includes a beam steering control function configured to convert the phase slope data to phase data to set the phase shifter element for that T/R module to a phase shift setting for the beam direction associated with the phase slope index data.

Techniques for maintaining beam pointing for an Electronically Scanned Antenna (ESA) as its frequency is varied over a wide frequency bandwidth. A technique uses discrete phase shifters, a number of stored states, and a control methodology for rapidly switching among the states.
