Abstract:

An expendable moving echo radiator suitable for providing a decoy to attract a homing torpedo and divert the torpedo away from its intended target is disclosed. The present invention provides an expandable and collapsible curtain for deployment from a capsule launched from a submarine or other sea vessel. In its expanded configuration, the curtain is characterized by a physical profile sufficient to reflect acoustic waves and to generate echoes substantially similar to echo signals generated by an actual, full size submarine or other target. The present invention is further provided with propulsion means, as well as means for enhancing its capability to capture a torpedos sensors. It can also be provided with explosives to destroy lured torpedoes. The expendable device can be used to simulate a submarine for anti-submarine warfare ASW training.
