线形声矢量阵一阶可调向差分波束形成器设计
First-order Steerable Differential Beamformer Based on Linear Acoustic Vector Sensors Array
摘要
Abstract
To address the issue that the main lobe of the linear first-order differential beamformers is unable to adapt to the moving target,a design method for a linear acoustic vector array first-order steerable differential beamformer is proposed.Firstly,the signal model and performance evaluation formula are derived based on the receiving signal model of a uniform linear array.Additionally,the beampattern and maximum directivity factor(DF)are defined.Finally,the sum of the channel weights and the propagation vectors of each channel are expanded based on McLaughlin's series,which is compared with the expression of the steerable differential beamformer,and then the channel weights are obtained.The simulation results demonstrate that,in comparison with the first-order differential microphone array,the algorithm exhibits superior directivity that almost remains consistent across frequencies.The experimental result in a pool illustrates that,in comparison with traditional acoustic pressure sensors,the array amplification after processing with the algorithm increases by 9 dB.This method is more conducive to underwater detection.关键词
