摘要
从军事潜艇通讯和民用水下通信的需求出发,制作了谐振频率150 kHz的单指向性平面水声换能器,并基于点对点通信原理设计了该换能器的发射和接收驱动电路。将该水声换能器置于水域中并接入电路实现了较远距离水下通信功能。在自主设计的实验平台上测试了该电路。测试结果表明,制作的换能器发射电压响应和灵敏度较高、指向性单一,水声通信电路具有频率可调性,通讯清晰稳定。该水声通信电路可用于军事以及民用领域通信,且便于移动和携带,易于调试。
Starting from the needs of military submarine communication and civil underwater communication,a unidirectional planar underwater acoustic transducer with a resonance frequency of 150 kHz was produced,and the transmitter and receiver drive circuit of the transducer was designed based on the principle of point-to-point communication.The underwater acoustic transducer was placed in water and connected to the circuit to realize the long-distance underwater communication function.The circuit was tested on a self-designed experimental platform,and the test results show that the fabricated transducer has a higher transmit voltage response and sensitivity,single directivity and the underwater acoustic communication circuit has adjustable frequency,clear and stable communication.The underwater acoustic transducer and the communication circuit which can be used for military and civilian communications is easy to move,carry and debug.
