二维声源定位算法仿真

Simulation Analysis of a Two - dimension Acoustic Localization Algorithm

文中提出新的高精度,快速二维声源定位算法。计算机采集四个声音传感器,一个风速传感器和一个风向传感器的信号,计算出声源的位置和当地的声速。用 MatLab 语言进行的仿真分析结果以及用 VB 所设计的交互式虚拟二维声源定位系统软件的使用表明,该算法是实用和有效的。

A new high resolution and fast two- dimension acousstic localization algorithm is proposed, in the paper. APC acqmres signals from four sound sensors, a wind speed sensor and a wind drrectlon sensor, and calculates the sound resource position and the local sound speed. The analysis results of a simulation program written in MatLab and the use of an interactive virtual two - dimension acoustic localization software written in VB show that the algorithm is practical and effective.
