摘要 利用LabVIEW软件开发了一套水声信号处理与目标方位估计的仿真演示系统。该系统针对水声信号的特点,搭建了信号发生、滤波处理、时频分析等处理单元,具有较强的水声信号处理能力。此外,将LabVIEW和MATLAB混合编程技术应用于水声信号处理中,实现了水下目标方位角的估计。仿真结果表明了该演示系统的有效性。 A simulation system for underwater acoustic signal processing and target localization has been developed in the paper.Aimed at the charcters of underwater signal,the system consists of the signal generator module,the signal analysis module,the DOA localization module and the communication module,all that consequently enables to deal with the complicated underwater signal.Especially,combined with the function of Matlab software,it can efficiently accomplish the target localization estimation.The performance shows that the system achieves great validity.
