Abstract

A torpedo countermeasure decoy which produces and broadcasts signals that e usually more attractive to a homing torpedo than those emanating from its intended target. Timely reset staircase generators combined with timely opened and closed gates generate stairstep signals which are added by a summing amplifier to produce a programmed composite signal thereof. A bank of voltage-controlled oscillators are driven by said composite signal in such a manner as to produce a predetermined plurality of discrete frequency signals within a predetermined plurality of consecutive but separated frequency bands within a given frequency spectrum, all of which are then effectively broadcast within the aqueous medium in the ambient environment of the torpedo's intended target--that is, the vessel to be protected.
