ABSTRACT:
2. In an echo-ranging torpedo wherein spurious and true-target echo signals ay be received in the listening periods between repetitive search-pulse transmission instants, in combination: a receiver operative to convert received echo signals to steering command signals having characteristics corresponding to echo-source direction, said receiver including a target-recognition circuit and a gating relay which operates, with inherent delay, in response to recognition of each true-target echo signal; a steering control circuit, including steering relay and switch means, adapted to place said steering relay and switch means in a condition corresponding to echo-source direction as derived by said steering control circuit, when operative, from said steering command signals; means applying said steering command signals to said steering control circuit; means controlled by operation of said gating relay, in response to each reception and recognition of a true-target echo signal, to render said steering control circuit operative to respond to steering command signals stemming from subsequent echo signals during a predetermined interval, of the order of a few listening periods, following each said reception and recognition of a true-target echo signal, and steering apparatus responsive, when rendered effective, to said steering relay and switch means condition; said gating relay, when operated, controlling said steering apparatus to render it effective to respond to said steering relay and switch means condition.
