Flightradar24 ADS-B receiver based on jetvision Radarcape [24]. Flightradar24 aggregates data from six sources: [25] Automatic dependent surveillance – broadcast (ADS-B). The principal source is a large number of ground-based ADS-B receivers, which collect data from any aircraft in their local area that are equipped with an ADS-B transponder and feed this data to the internet in real time.
A Royal Air Force Boeing E-3 Sentry over North Yorkshire. An airborne early warning and control (AEW&C) system is an airborne radar early warning system designed to detect aircraft, ships, vehicles, missiles and other incoming projectiles at long ranges, as well as performing command and control of the battlespace in aerial engagements by informing and directing friendly fighter and attack ...
This is a list of airborne early warning aircraft. An AEW aircraft is an airborne radar system generally used to detect incoming aircraft, ships, vehicles, missiles, and other projectiles and provide guidance to fighter and attack aircraft strikes.

Despite the progress, many abrupt events like sudden weather changes are not captured by existing flight trackers because they take their information not from the airplane itself but from dispatcher centers which often do not know the actual status of plane's whereabouts. [1]
The Northrop Grumman E-2 Hawkeye is an American all-weather, carrier-capable tactical airborne early warning (AEW) aircraft. This twin-turboprop aircraft was designed and developed during the late 1950s and early 1960s by the Grumman Aircraft Company for the United States Navy as a replacement for the earlier, piston-engined E-1 Tracer, which was rapidly becoming obsolete.
The radar mile is the time it takes for a radar pulse to travel one nautical mile, reflect off a target, and return to the radar antenna. Since a nautical mile is defined as 1,852 m, then dividing this distance by the speed of light (299,792,458 m/s), and then multiplying the result by 2 yields a result of 12.36 μs in duration.
Hughes' radar was initially thought to be a certain winner due to its related development of the APG-63 radar for the new F-15 Eagle. The Westinghouse radar used a pipelined fast Fourier transform (FFT) to digitally resolve 128 Doppler frequencies, while Hughes's radars used analog filters based on the design for the F-15.
