This invention relates generally to submarine boat simulating decoys and in particular to a sonar system for receiving the acoustical search pulse of an adverse or other vehicle and converting it into an elongated signal corresponding to the pulse that would be reflected from an actual maneuvering submarine boat and broadcasting said elongated signal back to said vehicle for deception and decoy purposes. In order to facilitate the training of sonar operators or the deception of an enemy conducting underwater warfare, it is often desirable and sometimes necessary to employ submarine vehicles that simulate the characteristics of actual submarine boats of the combat type in lieu of using real submarine boats themselves. So doing not only substitutes a lesser expensive and more portable device for a real submarine boat needed for other tasks in the former instance but makes use of a more expendable device as a decoy means, whereby life and more valuable property may be saved in the latter case.
