A new dimension-reduction method based on subarray architecture is proposed for solving problems in partially adaptive array processing. This method uses the smoothing array algorithm and divides the whole array into the overlapping subarrays to actualize dimension-reduction. This beamformer has a two hierarchical weighted structure. Based on the principle of the antenna map multiplication, this new beamformer is equivalent to the serial form of two spatial filter. Finally, simulation demonstrates the validity and superiority of the new algorithm.
