The earliest forms of stealth coating were radar absorbing paints developed by Major K. Mano of the Tama Technical Institute, and Dr. Shiba of the Tokyo Engineering College for the IJAAF. Multiple paint mixtures were tested with ferric oxide and liquid rubber, as well as ferric oxide, asphalt and airplane dope having the best results.
The A-12 included a number of stealthy features including special fuel to reduce the signature of the exhaust plume, canted vertical stabilizers, the use of composite materials in key locations, and the overall finish in radar-absorbent paint. [14] In 1960, the USAF reduced the radar cross-section of a Ryan Q-2C Firebee drone.
The Lockheed Have Blue was born out of a requirement to evade radar detection. During the Vietnam War, radar-guided SAMs and AAA posed a significant threat to US aircraft.. For this reason, strike aircraft during the war often required support aircraft to perform combat air patrols and suppression of enemy air defenses (SEAD).
Salisbury screens operate on the same principle as optical antireflection coatings used on the surface of camera lenses and glasses to prevent them from reflecting light. . The easiest to understand Salisbury screen design consists of three layers: a ground plane which is the metallic surface that needs to be concealed, a lossless dielectric of a precise thickness (a quarter of the wavelength ...
Reduce radar reflections from the airframe by the use of radar-absorbent materials (RAM) or radar-transparent materials such as plastics. Reduce radar detection from exposed internal surfaces such as the cockpit, weapons bay and engine intake ducting. Reduce infra-red and radar detection during adverse weather conditions [clarification needed]
Nakidka is efficient in the optical, IR and radar wavelength bands up to 12 cm (4.7 in), and also reduces the radar cross section by 10 db. [ 1 ] Nakidka weighs 2 kilograms per square metre (0.41 lb/sq ft) [ 1 ] and can be deployed in 0.4–1.0 man hours per square meter.
Target modifications include radar absorbing coatings and modifications of the surface shape to either "stealth" a high-value target or enhance reflections from a decoy. [1] Dispersal of small aluminium strips called chaff is a common method of changing the electromagnetic properties of air to provide confusing radar echos.
In the research facility in Russia, a cooperative but resentful Anton (Michael Aronov) tells Vasili (Peter Von Berg) that he needs two things to continue developing stealth technology: details of the radar-absorbent material used by the Americans, and a computer system called Echo that will allow him to test designs.
