Low complexity adaptive subarray configuration for FPGA implementation

Large scale adaptive beamformers require extensive computations and high speed low latency data transfer for FPGA implementation. A solution is to divide the full array into independent subarrays where each subarray spans most of the full array aperture. Individual subarrays contribute to the combined output and can be realized in a modular fashion. The performance of the subarray adaptive beamformer is shown close to that of the full array for a small number of interferences.
