NEXRAD or Nexrad (Next-Generation Radar) is a network of 159 high-resolution S-band Doppler weather radars operated by the National Weather Service (NWS), an agency of the National Oceanic and Atmospheric Administration (NOAA) within the United States Department of Commerce, the Federal Aviation Administration (FAA) within the Department of Transportation, and the U.S. Air Force within the ...
North Warning System. The North Warning System (NWS, French: Système d'alerte du nord) is a joint United States and Canadian early-warning radar system for the atmospheric air defense of North America. It provides surveillance of airspace from potential incursions or attacks from across North America's polar region.
Eglin AFB Site C-6 is a United States Space Force radar station which houses the AN/FPS-85 phased array radar, associated computer processing system (s), and radar control equipment designed and constructed for the U. S. Air Force by the Bendix Communications Division, Bendix Corporation. [5] [6] Commencing operations in 1969, the AN/FPS-85 was ...
The radar determines the direction because the short radio waves behave like a search light when emitted from the reflector of the radar set's antenna. Search RAF Boeing E-3 Sentry AEW1 with rotating radar dome. The dome is 30 feet across (9 m) The E-3 is accompanied by two Panavia Tornado F3.
In Call of Duty: Black Ops, the map "Grid" is placed in Pripyat near the Duga-1 array. A game later in the series, Cold War, uses the duga as location for a possible final mission and as a map in the Zombies game-mode “Outbreak”, the map being appropriately named "Duga". The said map has rappel lines that can take the player(s) up to the ...
Tethered Aerostat Radar System in New Mexico. The first aerostats were assigned to the United States Air Force in December 1980 at Cudjoe Key, Florida. During the 1980s, the U.S. Customs Service operated a network of aerostats to help counter illegal drug trafficking. Their first site was built at High Rock, Grand Bahama in 1984.
Doppler effect. The emitted signal toward the car is reflected back with a variation of frequency that depends on the speed away/toward the radar (160 km/h). This is only a component of the real speed (170 km/h). The Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842, is the difference ...
The AGM-88E was designed to improve the effectiveness of legacy HARM variants against fixed and relocatable radar and communications sites, particularly those that would shut down to throw off anti-radiation missiles, by attaching a new seeker to the existing Mach 2-capable rocket motor and warhead section, adding a passive anti-radiation ...
