Stealth technology, also termed low observable technology (LO technology), is a sub-discipline of military tactics and passive and active electronic countermeasures. [1] The term covers a range of methods used to make personnel, aircraft , ships , submarines , missiles , satellites , and ground vehicles less visible (ideally invisible ) to ...
The F-117 Nighthawk was the first operational aircraft explicitly designed around stealth technology. Other examples of stealth aircraft include the B-2 Spirit , the B-21 Raider , the F-22 Raptor , [ 3 ] the F-35 Lightning II , [ 4 ] [ 5 ] the Chengdu J-20 , [ 6 ] and the Sukhoi Su-57 .
Stealth helicopters are helicopters that incorporate stealth technology to decrease an enemy's detection ability. [1] There are a diverse range of technologies used to achieve this decreased detectability; these have largely involved the reduction of several different signatures typically generated by a rotorcraft, including those of noise ...
As opposed to an ordinary forward looking infrared system, an IRST system will actually scan the space around the aircraft similarly to the way in which mechanically (or even electronically) steered radars work. The exception to the scanning technique is the F-35's DAS, which stares in all directions simultaneously, and automatically detects ...
For example, a stealth aircraft (which is designed to have low detectability) will have design features that give it a low RCS (such as absorbent paint, flat surfaces, surfaces specifically angled to reflect the signal somewhere other than towards the source), as opposed to a passenger airliner that will have a high RCS (bare metal, rounded ...
In 1956, Texas Instruments began research on infrared technology that led to several line scanner contracts and, with the addition of a second scan mirror, the invention of the first forward-looking infrared camera occurred in 1963, with production beginning in 1966. In 1972, TI introduced the Common Module concept, which greatly reduced costs ...
