摘　　要：接收机是声纳系统的重要组成部分,为了满足工程开发和批量生产对接收机各项性能指标的自动化检测需求,本文设计了多通道宽带接收机测试系统。通过操作Qt编程环境设计的交互界面,即可完成整个测试过程,并将测试结果输出。本系统具有操作便捷、测试准确等优点,显著提高了系统开发过程中的工作效率,满足接收机性能指标的测试需求。本文主要介绍了系统设计方案、硬件及软件设计和待测指标的测试方法与实现,该系统能够普遍应用于声纳接收机测试。Sonar receiver is an important part of sonar system, in order to meet the demand for automatic detection of the receiver＇ s va- rious performance indicators in sonar development and production, this paper designed a multi - channel broadband receiver test system. By operating the interactive interface designed by Qt, testers can complete the whole test process, and get the test result. This system has the advantages of convenient operation and accurate test, which improves the work efficiency in system development and meets the requirements of sonar receiver＇ s performance test. This paper mainly introduced the system design scheme, hardware and software design, test method and implementation of the indicators under test. The system can be commonly applied to sonar receivers＇ test.
