摘　　要：介绍了水声信号定位系统的工作原理;基于LabVIEW的诸多优点,采用LabVIEW搭建了该系统的软件平台,提供了良好的计算机用户图形操作界面;针对水声信号的特点,搭建了滤波器、频谱分析等处理单元,具有较强的水声信号处理能力。此外,还将LabVIEW和MATLAB混合编程技术应用于水声信号处理,能达到更好的处理效果。仿真结果表明了该软件系统的有效性。This paper introduces the working principle of acoustic signal orientation system detailedly. And because of the merit, I.abVIEW is used for establishing software platform of the system, which means the computer can provide a good graphical user operation interface. Such details as filters and spectrum analysis units set up according to acoustic signal features make the system have strong acoustic signal processing capabilities. At one time the combined programming technology of LabVIEW and MATLAB is applied to acoustic signal processing to achieve better effect. The simulation results indicate the system＇s validity.
