Abstract: 1325794 Radio reflectors MESSERSCHMITT - BOLKOW - BLOHM GmbH 19 April 1971 [2 April 1970] 24907/71 Heading H4A Radar reflective "chaff" comprises units in the form of thin fibres provided with conductive coatings. Each fibre comprises carbonaceous material, at least on its surface, and this material either constitutes the conductive coating, or provides a base for a metallic coating. In one embodiment, fibres containing carbon or graphite are metallized by exposing them to nickel carbonyl vapour, so that a film of pure nickel is deposited on each. Other carbonyl forming metals, such as chromium, may be used instead of nickel. Another embodiment features graphite fibres coated with tungsten. These are heat resistant, and may be discharged with the exhaust gases of an aircraft or rocket propulsion unit. The fibres may be cut to half-wavelengths at a particular frequency. They may be provided with ferromagnetic coatings, so that they tend to align themselves along the earth's magnetic field, and selectively reflect waves having a particular direction of polarization.
