Sonar Transducer Application:



The piezoelectric ceramic materials that are most commonly used in sonar transducers and their relevant

materials properties are discussed . The most common piezoelectric ceramic-based projector designs for sonar applications are described.where they are grouped according to their operational frequency range. A single transducer cannot operate efficiently over the entire 1-kHz to 1-MHz frequency band – primarily due to impedance matching issues with the associated amplifiers.Consequently, a variety of transducer designs have been developed and optimized for different frequency ranges. When it is used to detect sound, it is called a receiver. Furthermore, when the receiver is employed underwater, it is referred to as a hydrophone. An underwater sonar system consists of projectors, hydrophones, and associated electronics such as amplifiers and data acquisition systems. however, will only cover the description and operational principles of the projector and hydrophone components. More specifically, the chapter will focus on piezoelectric ceramic-based transducer designs intended for underwater use that operate in the frequency band spanning from 1 kHz to 1MHz.
