【摘要】 针对便携式水声通信设备小体积和高效率的要求,设计并实现了一种水声信号发射机。该发射机具有效率高、抗于扰能力强、小型化的优点。其关键电路包括光耦隔离电路和匹配电路。进行了水池实验,测得发射机系统电声转换效率维持在20%-30%之间,表明该发射机可以应用于便携式水声通信设备。更多还原

【Abstract】 To satisfy the demand of portable underwater acoustic communication equipment for small size and high efficiency,an underwater acoustic transmitter is designed and implemented.According to the impedance of the transducer and SSM2305,the tuning matching and the pulse transformer are analyzed,and then matched filtering circuit is designed. The transmitter is verified in the tank experiment which shows that the systemic electro-acoustic conversion efficiency is 20%-30%,so the transmitter can be used in portable underwater acoustic communication equipment.更多还原
