一种新型的高频声呐发射机的研制

Development of a new high-frequency sonar transmitter

针对发射机的工作频率和发射功率的要求,设计并实现了一种高频声呐发射机。从基础理论出发,结合功率电路的理论、经验和设计方法,提出一种全新的高频声呐发射机的设计方案。对该声呐发射机进行了水池试验,在工作频率为5 MHz时匹配特定换能器可以满足发射功率要求。

A high-frequency sonar transmitter was designed and implemented according to the transmitter requirement for the operating frequency and transmitting power. Proceeding from the foundation theory, a new design scheme of the high-frequen- cy sonar transmitter is proposed in combination with the theory, experience and design method of the power circuit. The sonar transmitter was performed with the pool experiment. The sonar transmitter can meet the requirement of the transmitting power, when it is matched with a specific transducer, and its working frequency is 5 MHz.
