Sound waves are the only carriers that humans have mastered to transmit information and energy over long distances in the vast sea. people use electromagnetic waves to develop radars. Similarly, people use sound waves as information carriers to develop underwater acoustic transducer. Electronic equi

In the ultrasonic ranging system, the performance of the ranging algorithm directly affects the performance of the ranging system;The operation speed of the method directly affects the performance of the ranging system. From the perspective of information theory, the ultrasonic ranging process is ac

Mainly introducing the connection mode of the ultrasonic transducer array (auxiliary receiver) output port. The next chapter studies the design problem of the receiving and transmitting circuit of the disc-type piezoelectric transducer (main transducer), The circuit-assisted receiver array consists
