ABSTRACT:
An antenna comprised of a plurality of identical subarrays each having N antenna elements. The antenna elements of a core of subarrays all contribute outputs which are used for forming sum and difference beams. A peripheral area surrounding the core has subarrays which have a lesser number of antenna elements which participate in the signal processing operation to derive the sum and difference beams. The antenna elements of each subarray are combined in a manifold having one output, for the peripheral subarrays, and three outputs for the core subarrays. The manifold outputs are provided to various digital receivers which process the manifold signals with predetermined weighting functions. A digital beamformer processes the digital receiver outputs to derive the sum and difference beams which are used by a radar processor for tracking targets.
