分布式实时被动声定位系统研究

研究了一种基于PC104小基阵系统实现的分布式实时被动声定位系统，分别讨论了探测节点和控制中心两部分的原理结构。各节点具有独立探测声源方位角的功能，控制中心对各节点定位结果进行数据融合确定声源的精确方位坐标。系统结构简单，功耗低，适用于野外工作。外场实验结果证明，此系统可以实时地完成声目标的探测与定位任务，而且工作稳定，可靠性强。

Real-time Passive Localization by a Distributed Acoustic Array System

This paper presents the implementation of a small acoustic array system based on a micro computer system PC104,named array node,and hence a big distributed system made up of series of array nodes.Principles of the big system and localization algorithms of the small array have been discussed respectively.As we expect,nodes can calculate the source's azimuth and elevation,the big system can make out accurate coordinates of the source by means of data fusion.This system is quite simple with lower power,suitable for field detection.It is proved by series of field tests that this system can stably detect and localize different kinds of sources in real-time with high reliability.
