Abstract:
Piezoelectric transducers (PET) are widely used as emitters and receivers of acoustic signals to solve a great number of problems related to the study of the World Ocean. Providing the ability to operate the PET in the mode of short-sounding pulse radiation allows increasing the resolution of the remote sensing equipment of the aquatic environment. At the same time, a number of tasks require the use of non-directional emitters, for example, in the form of a thin-walled sphere. It is of interest to study the possibility of obtaining a short probing signal at the output of this type of PET. The paper considers the pulse mode of operation of a non-directional thin-walled spherical emitter excited by a short electrical signal. The research is based on the application of the method of equivalent circuits of the PET and the Fourier spectral method. The durations and amplitudes of the probing pulses emitted by the PEP are estimated. The results obtained may be applied to the design of equipment for underwater research.
