基于虚拟仪器技术的多路水声信号同步采集及处理平台设计

摘要

This paper describes an application of the virtual instrument technology in the area of the underwater acoustic signal processing. It realizes multiple-channel synchronous data acquisition, processing and memorizing in high sample rate based on LabVIEW language.It also realizes the real time processing of 32-channel conventional beamforming (CBF) on the single-core CPU of the main control board without DSP platform. Meanwhile, this paper presents some tentative research results on the realization of real time signal processing with non-DSP platform.%本文介绍了虚拟仪器技术在水声信号处理研究中的一个具体应用,利用LabVIEW语言编程,在NI公司高速数据采集硬件平台上实现了高采样率下多通道数据的同步采集、处理、记录功能,并在不使用信号处理机的情况下,利用主控单板机的单核CPU完成了32通道常规波束成形(CBF)的实时计算.同时,本文对非DSP硬件平台的实时信号处理实现方法进行了初步的研究.
