Abstract This letter deals with adaptive H ∞ ‐array beamforming based on a generalized sidelobe canceler with and without a subweight partition scheme. It is shown that the adaptive H ∞ ‐beamformer with a subweight approach demonstrates the advantages of faster convergence speed, insensitivity to dynamic estimate error, and more suitable arbitrary noise signals compared to the conventional H ∞ adaptive algorithm and RLS‐based beamformer. Several computer simulation examples are provided to illustrate the effectiveness of the proposed technique. © 2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 24: 202–206, 2000.
