Abstract : A wide angle, wide bandwidth sonar transducer comprising a spherically curved array of transducer elements fully embedded in a body of acoustically transparent potting compound with their axes extending radially outwardly of a spherically curved wall to which they are bonded. Each includes an aluminum load element bonded to a piezoelectric element and is characterized by an electrical terminal press fitted into the load element. A method of manufacture for achieving the desired array formation within the potting compound utilizes a pattern from which a form is cast to hold the transducer elements in formation while being bonded to the curved wall, after which the form is removed and additional potting is cast.
