No world is a stage, and you cannot detect a helicopter unless you have the radar station (radar alone is not sufficient)
Radar!
As far as I know, radar was invented by a Hungarian scientist named Zoltan Bay. That radar was first used in World War II by the British troops.
Normal radar sends out radio waves to determine the location of an object. Doppler radar can not only find the location of an object or storm, but using something known as the Doppler effect can determine how fast it is moving towards or away from the radar.
tracking radar
a stealth plane has the normal components of any other aircraft. the main difference is the exterior design of the aircraft. a stealth plane \s body is made at high angles to help deflect enemy radar. they also use radar absorbant paint so the radar pick up is nil or similar to that of a small bird.
Shape and a special covering that renders invisible to radar
The F-22 is the plane undetectable by radar, but it is said that the B-1 looks like a flock of birds on radar.Being undetectable or nearly undetectable on RADAR is known as stealth. There are several stealth aircraft currently in use in the United States armed forces. The F-22 "Raptor" is one of them. . The B-2 "Spirit" Stealth bomber is yet another. The newest in the line of fighter aircraft, the F-35 "Lightning II" is also stealth capable, as well as VTOL (vertical take off and landing) capable in the model for the Marines. The F-117 "Nighthawk" is another stealth aircraft, but has been retired due to obsolescence.For more information, visit the link below:
Stealth technology is a specialized technology that reduces the visibility of an aircraft or military asset to radar, infrared, and other detection methods. It uses design features and materials that absorb or deflect radar waves, making the asset less detectable by enemy sensors. Stealth technology aims to make military assets more difficult to track or target, improving their survivability in combat situations.
the stealth fighter has a classified mixture of a special kind of aircraft paint that the radar cant read. Answer: Stealth is "designed in". It relies upon the shaping of the airframe, (although stealth paint can help).
The antonym for radar is stealth. Radar is a system that detects the presence, direction, and distance of objects by radio waves, while stealth refers to the ability to go undetected by radar or other detection systems.
Stealth bombers remain visible to the naked eye, the "stealth" part comes from its decreased visibility to a radar. The plane's design (both its shape and the materials used) is such that it reflects radar signals in a way which makes it more difficult for the machine to detect it. This in turn makes targeting and attacking the bomber difficult, even if it can be normally seen.
Both the F-22 and the F-35 are stealth capable aircraft.
the plane is made with radar absorbent material, and is shaped specifically so the radar that doesn't get absorbed, deflects off of it at an angle and not back to the ground based radar. it has been rated as the best bomber till now in the world.
Any radar can detect a stealth jet BUT only at very close ranges depending on the radar cross section of the jet. Therefore, stealth provides first lock, first shoot, first kill capability
Stealth aircraft are not actually invisible to radar, but the waves reflected by it are far fewer than what is needed for identification as a plane. 1) The first way that it prevents this is by its shape, which reflects radar waves in random directions, rather than back to the receiver. 2) Secondly, the special paint used has the ability to absorb electromagnetic energy in the same frequency as radar impulses. 3) Finally, the mission profiles often allow stealth aircraft to fly close to the ground, where their radar return can be lost in ground clutter.
All stealth aircraft are built with the intent of being 'invisible' to radar. One of the best was the F-117.
