Abstract:
An array system, comprising:a plurality of antenna elements divided into a plurality of subarrays; a summing network for each subarray for combining the signals from each antenna element in a subarray to provide for each subarray a subarray signal; phase shifting apparatus for selectively introducing a signal routing phase shift of 0Â° or 180Â° to the respective subarray signals; a monopulse combiner responsive to the subarray signals to provide a plurality of combiner outputs; a plurality of receivers each having an input connected to receive a corresponding combiner output for processing the monopulse combiner outputs; a controller for providing phase shift commands to the phase shifting apparatus to modulate the phase shift of the phase shifters of selected subarrays by adding a subarray phase shift of 0Â° or 180Â° to dynamically effect the routing of the monopulse array output signals to desired ones of said receivers.
