Stealth technology (or LO for low observability) is not one technology. It is a set of technologies, used in combinations, that can greatly reduce the distances at which a person or vehicle can be detected; more so radar cross-section reductions, but also acoustic, thermal, and other aspects.
Passive (multistatic) radar, bistatic radar [25] and especially multistatic radar systems detect some stealth aircraft better than conventional monostatic radars, since first-generation stealth technology (such as the F-117) reflects energy away from the transmitter's line of sight, effectively increasing the radar cross section (RCS) in other ...
Plasma stealth is a proposed process to use ionized gas to reduce the radar cross-section (RCS) of an aircraft. Interactions between electromagnetic radiation and ionized gas have been extensively studied for many purposes, including concealing aircraft from radar as stealth technology .
System design was initiated on a mobile chassis in 1999, after NATO countries intervened in the Federal Republic of Yugoslavia, in which the stealth F-117 [4] participated - one was shot down by S-125 Neva with help of P-18 radar - Russia started to perceive stealth aircraft as a possible future threat to their security.
(A stealth missile works in much the same way as an aircraft, employing stealth technology—radar-absorbing material, smooth surfaces, and a flat exhaust system—to make it less observable to ...
The Pave Mover radar demonstrators provided the non-stealth portion of the program's targeting system, whereas Tacit Blue was intended to demonstrate a similar but stealth capability, while validating a number of innovative stealth technology advances. [1] The radar sensor technology developed for Tacit Blue evolved into the radar now being ...
Radar cross-section (RCS), denoted σ, also called radar signature, is a measure of how detectable an object is by radar. A larger RCS indicates that an object is more easily detected. [1] An object reflects a limited amount of radar energy back to the source. The factors that influence this include: [1] the material with which the target is made;
Iran has an air defense system that would require stealth technology to penetrate. [ 21 ] [ 22 ] In December 2009, South Korea 's JoongAng Daily newspaper reported that the RQ-170 Sentinel had been test-flown in South Korea for the past few months and that it was expected to be permanently deployed in 2010 to replace Lockheed U-2 reconnaissance ...
