Abstract
An acoustic homing torpedo having an array of transducers wherein each transducer has a head mass, tail mass, and a main active element therebetween. An auxiliary active element is placed on the tail mass so that when given a predetermined signal it will cause the main element to provide a corresponding output signal so as to simulate the reception of an actual acoustic wave. By energizing the main element, the response of the auxiliary element may be examined for testing the transducer and the array in a transmit mode of operation.
