Abstract: An acoustic imaging system for a wire guided torpedo having an array of tsducers arranged in the nose of a torpedo to receive acoustic signals. A spherical acoustic lens focuses the signals on the array of transducers. The outputs of the transducers are amplified, integrated, detected and passed to a set of gates which are sampled sequentially, and the outputs of the gates are passed by a wire to the launching vehicle.
