摘　　要：针对水声工程专业学生难以在有限时间的实验教学过程中完成整套声呐系统的设计,并在实际声呐系统环境下对设计功能电路进行调试的问题,提出并实现了一种模块化的声呐实验教学装置。该装置主要由收发换能器、信号产生模块、功率放大模块、信号调理模块、数据采集模块、信号处理与控制模块、显控模块、接口模块、数据传输模块等部分组成,各模块与底板之间全部采用灵活的可插拔接口设计方案,便于学生后期的开发调试。测试表明,装置稳定性及可靠性均达到了预期设计指标,并已应用于本科生实验教学中,教学效果良好。It is difficult forunderwater acoustic engineering students to complete the design of the whole sonar system in the experimental teaching process for a limited time,and to debug the design function circuit in the actual sonar system environment,and propose a modular sonar experiment teaching.The system consists of a transceiver transducer,a signal generation module,a power amplification module,a conditioning and acquisition module,a signal processing and control module,a display control module,an interface module,and a data transmission module.The flexible pluggable interface design scheme is adopted between each module and the backplane,which is convenient for students to develop and debug later.Tests show that the system stability and reliability have reached the expected design indicators,and has been applied to undergraduate experimental teaching.The teaching effect is good.
