Abstract
Method and apparatus for guiding an acoustic torpedo toward a ship selected as target which, as a defence against torpedoes drags noise generating decoys (so-called disturbance generators) wherein the torpedo is acoustically guided toward the noise source having the greatest noise level for the torpedo. As the torpedo approaches the noise source a check is made for the presence of a wake, and after detection of a wake in the immediate vicinity of the noise source during passage of the torpedo underneath the noise source, a check is made for the minimum expanse of the noise source in the vertical and travelling direction of the torpedo. The torpedo is set to search for a further noise source if no wake is detected or if a wake is detected in the vicinity of the noise source but a predetermined minimum expanse for the noise source is not detected.
