非均匀声矢量线阵差分波束形成方法
A Differential Beamforming Method Based on Non-Uniform Linear Acoustic Vector Sensor Array
摘要
Abstract
In order to improve the robustness of the differential beamformer,a differential beamforming method based on non-uniform linear acoustic vector sensor array is proposed in this paper.The design of ideal steerable differential beampattern is realized by distortionless constraint and extreme value constraint,and the minimum-norm solution based on the McLaughlin series is obtained by comparing the beam response with the ideal steerable differential beampattern.The effect of the sensor spacing on white noise gain under a non-uniform linear array is theoretically analyzed,and it is demonstrated that the design of a robust differential beamformer can be achieved after optimizing the position of the sensors.Unlike the traditional differential method,the proposed method can enhance the robustness of the differential beamformer without loss of spatial gain.Numerical simulations are used to demonstrate that the proposed method can realize steering with higher spatial gain under non-uniform linear array.关键词
