中文摘要:
      高频换能器接长电缆后谐振频率会发生偏移,导致与工作频率相差甚远,工作点的导纳值与不接长电缆时偏差较大。这使得换能器与发射机和接收机之间的阻抗严重失配。文章对高频长缆水声换能器匹配技术进行研究,通过建立换能器等效电路模型,利用传输线理论,进行四端口匹配网络的设计和仿真,并制作一块匹配电路板。实验结果表明,系统匹配性测试与仿真计算相吻合,提高了系统机电转换效率,证明了该匹配方法的可行性和工程实用性。
英文摘要:
      After the high-frequency transducer is connected with a long cable, the resonant frequency drifts away from the operating frequency, and the admittance value at the working point deviates greatly from that without the long cable, which causes impedance mismatch between the transducer and the transmitter and receiver. In this paper, the characteristics of the high-frequency underwater acoustic transducer with long cable are studied. By establishing the equivalent circuit model of the transducer and using the transmission line theory, the four port matching network is designed and simulated, and a matching circuit board is made. The experimental results show that the tested system matching performance is consistent with the simulation calculation, which improves the electromechanical conversion efficiency of the system, and proves the feasibility and engineering practicability of this method.
