Ultrasonic Acoustic Transducer for Marine Detection

With the deepening of marine development, the related technologies for underwater exploration have been paid more and more attention. The key technologies of underwater acoustic detection are ultrasonic underwater acoustic transducer and signal processing. 

Ultrasonic underwater acoustic transducer remote control system framework, application, development In recent years, due to military and marine development requirements, people began to pay more and more attention to underwater communication system research and development. As the electromagnetic waves in the water when the attenuation is serious. The sound waves are the only energy forms known to mankind so far in the water long-distance transmission, so the ocean detection, communication, positioning and navigation of the main use of sound waves. Underwater acoustic transducer is the sound energy and electrical energy conversion devices. The position in the sonar is similar to that of an antenna in radio equipment and is an acoustic system that emits and receives sound waves in seawater. The transducer that converts acoustic energy into electrical energy is called a receiver or hydrophone; a transducer that converts electrical energy into acoustic energy is called a transmitter. Some sonars use the same transducer to transmit and receive sound waves - some use separate transmitters and hydrophones.
