Description

[0001] technical field

[0002] The invention belongs to the technical field of underwater acoustic transducers, and in particular relates to a dish-shaped emitting transducer. The transducer can be applied in the fields of low-frequency active sonar (LFAS), long-range underwater acoustic communication, submarine acoustic tomography, exploration and development of marine resources, and the like. Background technique

[0003] The 21st century is the century of the ocean. Sound waves are the only information carriers capable of traveling long distances in the ocean. In the military field, acoustic methods are the main means of underwater target detection, positioning, identification, navigation, and communication; in the civilian field, acoustic methods play a pivotal role in offshore oil and natural gas resource exploration and submarine formation imaging.

[0004] With the development of target stealth technology, traditional passive sonar is losing its dominant position. Lo...
