摘要：

A knowledge-based adaptive beamforming approach that is robust to low sample support environment is proposed. In this algorithm the covariance matrix used to calculate the optimum weights is constructed by blending a sample covariance matrix and a priori structured covariance matrix. Numerical examples demonstrate the proposed algorithm has the advantages over the standard Capon beamformers.
