Can someone actually "fly under the radar"?
WebA radar system detects other aircraft, ships, or other objects and the speed and direction in which they travel by sending out a pulse of high-frequency electromagnetic waves. This pulse goes out ahead of the aircraft until it … Radar is a radiolocation system that uses radio waves to determine the distance (ranging), angle (azimuth), and radial velocity of objects relative to the site. It is used to detect and track aircraft, ships, spacecraft, guided missiles, and motor vehicles, and map weather formations, and terrain. A radar system … See more First experiments As early as 1886, German physicist Heinrich Hertz showed that radio waves could be reflected from solid objects. In 1895, Alexander Popov, a physics instructor at the See more Radar signal A radar system has a transmitter that emits radio waves known as radar signals in predetermined directions. When these signals contact an object they are usually reflected or scattered in many directions, although some of … See more A radar's components are: • A transmitter that generates the radio signal with an oscillator such as a klystron or a See more Radar come in a variety of configurations in the emitter, the receiver, the antenna, wavelength, scan strategies, etc. • See more The information provided by radar includes the bearing and range (and therefore position) of the object from the radar scanner. It is thus used in many different fields where the need for such positioning is crucial.
