The Raytheon Sentinel is a retired airborne battlefield and ground surveillance aircraft formerly operated by the Royal Air Force (RAF). While based on the Bombardier Global Express ultra long-range business jet, the prime contractor for the Sentinel was the American defence firm Raytheon, which supplied most of the mission systems and performed the integration work.
It is currently produced by Raytheon Missiles & Defense. First built in 1995 as a modification of AN/TPQ-36A for search and track role in the Norwegian NASAMS air defense system, the Sentinel radar is deployed with forward area air defense units of the U.S. Army. Mounted on a towed platform, it can be positioned remotely from the rest of the unit.
The AN/AWG-9 offers multiple air-to-air modes: long-range continuous-wave radar velocity search, range-while-search at shorter ranges, and an airborne track-while-scan mode with the ability to track up to 24 airborne targets, display 18 of them on the cockpit displays, and launch against 6 of them at the same time. This function was originally ...
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.
