Transcript of How does stealth technology shield aircraft from radar

how does stealth technology shield aircraft from radar Stealth technology also termed LO technology
(low observable technology)
is a sub-discipline of military tactics and passive electronic countermeasures,
which cover a range of techniques used with personnel,
aircraft, ships, submarines, and missiles, to make them less visible (ideally invisible) to radar,
infrared,sonar and other detection methods. With regard to radar, there are two components to stealth - absorption and deflection. Through the shape of the object, it is possible to deflect the radar waves away from the source. And with special materials (iron ferrites generally) it is possible to absorb a large portion of the radar. Some times the cartels use the stealth technology
for transport drugs or people to the U.S.They used stealth technology in boats when it more amount. This is the main method employed for locating aircraft, for both civilian and military purposes, and involves bouncing a radio signal off an object, which can then be detected by a receiver. Stealth aircraft defeat this in two different ways. Firstly, surfaces on the aircraft are constructed out of radar absorbent or transparent material. Secondly, structures within the aircraft are designed to minimize the size of flat areas, which would reflect a signal back at the radar. The structure is built with lots of different facets. When a radar beam hits the aircraft, the radar's energy is deflected away at many different angles so very little of the radar energy is reflected back at the radar receiver.
