Abstract :
Details are given of an underwater transducer which is tunable over the frequency range 250 kHz to 700 kHz. The structure comprises a pair of 50 mm-diameter lead zirconate titanate ceramic plates suitably mounted. The resonant frequency of the structure is electronically controlled by varying in a predetermined manner the amplitude and phase of the voltage applied to one of the ceramics.
