摘要：

Consider the complexity of the ocean circulation, unlike the conventional beamforming, the minimum variance distortionless response beamforming (abbreviated to MVDR) is able to respond to the change of the interference of space environment. MVDR beamforming could make a null steering in the direction of the interference so as to enhance the SINR (i.e. signal-to-interference-plus-noise) of the system. In this paper, different ways of estimating covariance matrix are adopted to infer the weight vector and the corresponding beam response. Then, emphasis is placed on the effect of the input signal-to-noise (SNR) and snapshots. Finally, through Matlab simulation, the conclusion that the actual MVDR beamforming is more likely influenced by the input SNR may be drawn.
