Abstract
A method of protecting a ship from missiles with two-color infra-red target seeking heads and which is characterized in that an interference transmitter disposed on the ship sends out exclusively short wave infra-red rays, at least intermittently, the strength of radiation from the interference transmitter being so adjusted that the ratio of short wave to medium wave infra-red radiation is so shifted that the ship cannot be reliably recognized as a target by the two-color infra-red target seeking head.
Claims17
A method of protecting a ship from missiles with two-color infra-red target seeking heads, comprising:
- providing an interference transmitter on the ship emitting short wave infra-red rays at least intermittently, and adjusting the intensity of the radiation from the interference transmitter to shift the ratio of short wave to medium wave intra-red radiation so that the ship cannot be reliably recognized as a target for a missile having two-color infra-red target seeking head.
A ship assembly providing protection from missiles with two-color infra-red target seeking heads comprising:
- (a) a ship;
- (b) an interference transmitter on said ship emitting shortwave infra-red rays at least intermittently;
- and
- (c) means for adjusting the intensity of the radiation emitted to shift the ratio of short wave to medium wave infra-red radiation so that the ship cannot be reliably recognized as a target for a missile having two-color infra-red target seeking head.
