| 摘 要： | 为了便于探鱼声纳更好的应用于小渔船，其换能器基阵应简易轻便，易于安装，因此把换能器的匹配网络放在干端，减小换能器基阵的体积与重量。为解决长线传输过程中换能器的阻抗匹配，提出了一种匹配方法，在实际应用中很好地解决了超声换能器的宽带阻抗匹配。

| Abstract: | In order to explore the application of sonar fish better in small fishing boats, the transducer array should be simple and portable, easy to install, so the transducer matching network on the dry side, reducing the transducer array the volume and the weight of the. In order to solve the impedance matching of transducer in long line transmission, a matching method is proposed, and the broadband impedance matching of ultrasonic transducer is well resolved in practical application.. |
