Robust adaptive beamforming method for vector hydrophone arrays
摘要
Abstract
To address the problem of suppressing strong interference sources using vector hydrophone arrays,a robust adaptive beamforming method based on the worst-case performance optimization(WCPO)criterion is proposed.The WCPO criterion is incorporated into the Capon beamforming framework for vector arrays.A constrained optimization model is formulated by taking the upper bound of the expected steering vector random error as a constraint,enabling optimal beamformer design under the condition of maximum steering vector mismatch.The Lagrange multiplier method is employed to solve the established model,and the Newton iteration method is utilized to determine the Lagrange multipliers,yielding the adaptive beamforming weight vector.Computer simulations for one-dimensional and two-dimensional adaptive beamforming are conducted,and the results demonstrate that the proposed method effectively suppresses the specified strong interference sources in the presence of steering vector mismatch.关键词
