1. In an electronically scanned phased array antenna system including an array of antenna elements and a phase shifter corresponding to each antenna element in said array for adjusting the phase of the signal associated with said corresponding antenna element, said each phase shifter being governed by a computed phase shift value, the plurality of which effecting a phased array on the signals of the antenna elements for pointing the antenna beam in a desired direction;

  • a phase shift controller corresponding to each phase shifter for individually computing said phase shift value which governs said corresponding phase shifter, each phase shift controller being preprogrammed with a predetermined phase shift value increment to compute a sequence of phase shift values in accordance with a predetermined time pattern, thereby governing the scan of the antenna beam in a corresponding sequence of desired directions.
