A underwater acoustic signal monitoring system based on data acquisition (DAQ) card PCI8602 and program-ming software LabVIEW was designed to improve underwater acoustic signal monitoring effect and ability. The system takes the hydrophone RHSA20 as the front sensor to connect the signal regulate model,and uses DAQ card PCI8602 as the core hardware to realize the real-time DAQ,display and storage of the underwater acoustic signal with LabVIEW quickly. It can meet the re-quirements of the underwater acoustic signal monitoring.%为了提高水声信号监测效果和能力，设计了一种基于PCI8602数据采集卡和LabVIEW编程软件的靶标水声信号监测系统。系统采用RHSA20标准水听器为前端传感器，连接信号调理模块，以PCI8602数据采集卡为核心硬件，通过LabVIEW编程软件快速实现对水声信号的实时数据采集、显示与存储，可满足对水声信号的监测需求。
