摘要

构建了基于测向交叉定位法的分布式声源定位实验系统。首先

利用四元十字阵节点通过到达时间差（TDOA）方法计算声源位置角度

然后

通过测向交叉定位法融合各节点角度

计算声源位置。通过该系统实验测试了测向交叉定位法在实际应用中的性能。该系统在声源距离阵元50 m时定位误差为2.9 m

声源距离阵元100 m时

定位误差为5.8 m。实验结果表明:测向交叉定位法在实际应用中能准确计算出声源位置

定位误差随麦克风与目标的距离增大而增大。

Abstract

Distributed acoustic source localization experimental system based on direction finding cross locating method is constructed. First

calculate angle of sound source position through TDOA method of four-element cross array node

then fuse angle of each node by direction finding cross localization method

calculate location of sound source. Performance of direction finding crossing locating method in practical application is tested by the system.The localization error is 2. 9m when the distance between microphone and acoustic source is 50m

and when the distance is 100m

the localization error is 5. 8m. Experimental result show that direction finding crossing locating method can calculate the location of sound source accurately in practical applications and localization error increases with the distance between microphone and target.
