Abstract
There is provided an apparatus and method for disrupting radar systems. The apparatus comprises a chamber (110) for attachment to a vehicle, a radar countermeasure material (130) in the chamber, the radar countermeasure material comprising a plurality of hollow fibres, wherein the inner surface of at least some of the hollow fibres is at least partly coated with a conductive substance, and a release means (140) for dispensing the radar countermeasure material out of the chamber.
Claims18
An apparatus (100) for disrupting a target radar system, comprising:
- a chamber (110, 310, 320) for attachment to a vehicle;
- a radar countermeasure material (130) in the chamber, the radar countermeasure material comprising a plurality of hollow fibres made of an insulating material, wherein the inner surface (220) of the hollow fibres is at least partly coated with a conductive substance (225) and wherein the outer surface of the plurality of hollow fibres is non-conductive;
- wherein said outer surface (210) of said hollow fibre has no coating, and said conductive substance coating (225) has no overcoating;
- and
- a release means (140) for dispensing the radar countermeasure material out of the chamber.
A method for disrupting radar systems, comprising the steps of:
- providing a radar countermeasure material;
- and
- dispensing said radar countermeasure material (130), wherein the radar countermeasure material comprises a plurality of hollow fibres made of an insulating material, wherein the inner surface (220) of the hollow fibres is at least partly coated with a conductive substance (225) and wherein the outer surface of the plurality of hollow fibres is non-conductive;
- wherein production of said plurality of hollow fibres comprises a step of applying said inner surface conductive substance coating (225) to said inner surface (220) of said plurality of hollow fibres;
- and
- wherein said outer surface (210) of said hollow fibre has no coating, and said conductive substance coating (225) has no overcoating.
A system (100) for disrupting a target radar system, comprising:
- a chamber (110, 310, 320) for attachment to a vehicle;
- a radar countermeasure material (130) in the chamber;
- said radar countermeasure material comprising:
- a plurality of hollow fibres made of an insulating material;
- wherein an internal diameter (240) of the hollow fibre is greater than about 50% of an outer diameter (230) of the hollow fibre;
- wherein the inner surface (220) of the hollow fibres is at least partly coated with a conductive substance (225) and wherein the outer surface of the plurality of hollow fibres is non-conductive;
- wherein the conductive substance inner coating (225) is exposed and electroplated on the inner surface;
- wherein a thickness of the conductive substance (225) is about 100 nm and has a controlled thickness;
- wherein said outer surface (210) of said hollow fibre has no coating, and said conductive substance coating (225) has no overcoating;
- and
- a release means (140) for dispensing the radar countermeasure material out of the chamber, whereby the target radar is disrupted.
