摘要

基于传声器阵列和互相关算法的时间延迟技术对声源进行定位

互相关算法对宽频带信号（扫频信号）定位比较准确

对窄带信号（风琴信号）定位不显著

分析了影响声源定位精度的因素

并改进声源定位系统。通过实验验证了影响风琴信号声源定位的因素

实现了风琴信号的声源定位

并在NI CompactRIO系统上开发了一个实时声源定位系统。

Abstract

Time delay technology based on microphone array and cross-correlation algorithm is used for sound source localization

cross-correlation algorithm for wideband signal（sweep signal） localization is accurate

for narrowband signal（organ signal） localization is less significant

analyze factors which impact precision of sound source localization

and improve sound source localization system.Verify factors that affect sound source localization of organ signal

through experiments

achieve sound source localization of organ signal

and develop a real-time sound source localization system based on NI CompactRIO system.
