摘要

本文研究了应用于声场HanburyBrown-Twiss(HBT)干涉空间被动定位方法中的传感器阵列拓扑结构，优化了传感器阵列结构，实现了对目标声源的精确定位.基于理论和仿真，对多种拓扑结构的阵列进行参数影响分析，通过空气中的声源定位实验，对所设计的拓扑结构进行验证.结果表明，当阵元间距在20~100 cm范围内，阵间距为7.5 m时，综合性能最优的拓扑结构为双五元阵.实验结果和仿真保持一致，实现了在阵元间距1 m情况下对56.5 m远处声源的定位，误差为0.3 m.

Abstract

The sensor array topology applied to the Hanbury Brown-Twiss (HBT) interference space passive positioning method is studied and optimizes the sensor array structure in this paper

accurate positioning of target sound source is achieved. Based on theory and simulation

the influence of array parameters on various topological structures is analyzed

the designed topology is verified by the acoustic source location experiment in the air. The results show that when the array element spacing is in the range of 20cm~100cm and the array spacing is 7.5m

the optimal topological structure is double five-element array.The experimental results are consistent with the simulation resultsand indicate that the target with 56.5meters distance from sensor array (Array elements spacing of 1 meter) is accurately positioned and the error is lower than 0.3m.
