TO THE QUESTION ON THE REDUCTION OF ACOUSTICAL PULSE DURATION OF THE TRANSDUCER EXCITED BY PULSES OF THE SPECIAL SHAPE

The pulse mode of operation of the piezoelectric transducer as a plate is considered. One side of the plate is loaded on the water medium, and another - on air. At carrying out of research method d'Alembert was used. On the basis of numerical-theoretical researches shapes of radiated acoustic pulses in water are defined at excitation of a plate by electric pulses of special shape. The opportunity of radiation of short acoustic signals is shown at excitation of the transducer by pulses of electric excitation of the special form
