1. In an acoustic homing torpedo of pulse-echo type having means for converting received target echoes to output signals defining the sense of target direction referenced to torpedo heading, in combination, means controlled by said output signals for providing target direction samplings in the form of charge increments which are substantially uniform but of sign corresponding to the sense of target direction, means for decaying each of said samplings in accordance with a predetermined time-function to provide weighting which favors the most recent sampling, means for providing a continuous algebraic cumulation of the decaying samplings, means for providing a steering command signal having characteristics varying in accordance with the varying sign and magnitude of the said algebraic cumulation, and torpedo steering means controlled by the steering command signal and in accordance with said characteristics thereof to provide target homing action in which the sense and rate of torpedo turns correspond to the varying sign and magnitude, respectively, of said algebraic cumulation.
