摘要: 对一定区域内的声源目标定位是声学技术的研究方向之一。借鉴TDOA算法被动定位思想,并针对声信号特点,可设计基于TDOA协同被动定位算法的声场监测系统,用于在空旷场地进行声源监测定位。该系统通过在空旷场地布放3个或多个高灵敏度麦克风监测声目标源,通过计算各麦克风收到信号的时间差,采用Chan和Taylor联合算法,可实现对一定区域内的声目标定位。经过在空旷地实测数据仿真表明,该系统可成功对声目标进行定位,且性能稳定。

关键词: TDOA,声定位,Chan算法,Taylor算法

Abstract: Acoustic source location is one of the research point in the acoustic technique.In this paper,we firstly use the idea of TDOA (Time Difference of Arrival) in the acoustic location system design;Putting three or more microphones in the open area,collecting acoustic signal and calculate the time delay between the different microphones,then use a new cooperative location algorithm based on Chan and Taylor algorithm to estimate the target location.The simulations and tests indicate this system can effectively locate the acoustic target in open area,and has stable performance.

Key words: TDOA,Acoustic location,Chan algorithm,Taylor algorithm
