摘　　要：针对水声宽带信号复杂和功率放大匹配困难的问题,提出基于虚拟仪器技术的水声宽带功率放大及匹配系统发生器设计方法,并以LabVIEW(Laboratory Virtual Instrument Engineering Workbench)为平台设计开发了用于水声发射换能器的选择、阻抗匹配网络选择以及发射机使能状态信息控制等多功能水声宽带功放信号发生控制系统。该系统可以根据需求自定义选择配置发射连续或脉冲信号,运行测试其可以实现对发射功率大小、信号形式、阻抗匹配网络等参数选择,且减少了硬件开销,操作简便,便于推广。In view of underwater acoustic complex broadband signal and power amplification matching difficulties of problem, there presenting underwater acoustic broadband power amplifier and matching system generator methods based on virtual instrument technolo- gy, and designed the muhifunction underwater acoustic broadband amplifier signal generator and controller system for underwater sound transmitting transducer the choice, the impedance matching network choice as well as the transmitter condition message control based on LabVIEW. The system can be customized according to your demand to choose whether launching continuous or pulse signal, and it will further implementation on launches amplifier power, signal forms, impedance matching network parameters. The result of actual tests shows the underwater acoustic broadband amplifier signal generator and controller system could reduce the hardware expenses, also the system is advantageous for the promotion by using simple operation.
