  2. Bay News 9 - Wikipedia

    en.wikipedia.org/wiki/Bay_News_9

    In 2002, Bay News 9 was the first TV station in the area to provide a VIPIR Doppler weather radar system. In 2007, Bay News 9 became the first station in Florida, and one of only a handful of stations, to provide a Dual-Pole Doppler Radar system. On Monday, January 5, 2009, Bay News 9 launched its upgraded doppler radar system called Klystron 9 ...

  3. Klystron - Wikipedia

    en.wikipedia.org/wiki/Klystron

    A klystron is a specialized linear-beam vacuum tube, invented in 1937 by American electrical engineers Russell and Sigurd Varian, [1] which is used as an amplifier for high radio frequencies, from UHF up into the microwave range. Low-power klystrons are used as oscillators in terrestrial microwave relay communications links, while high-power ...

  4. Airport surveillance radar - Wikipedia

    en.wikipedia.org/wiki/Airport_surveillance_radar

    An airport surveillance radar (ASR) is a radar system used at airports to detect and display the presence and position of aircraft in the terminal area, the airspace around airports. It is the main air traffic control system for the airspace around airports. At large airports it typically controls traffic within a radius of 60 miles (96 km) of ...

  5. Russell and Sigurd Varian - Wikipedia

    en.wikipedia.org/wiki/Russell_and_Sigurd_Varian

    The klystron, a microwave tube, was noticed in 1938 by Sperry Gyroscope, who gave the Varian brothers and Hansen a contract to do further work. The Varians did not know that the British were also working on early radar technology, which by then could detect submarines, but could not be made light enough to use in airplanes. [10]

  6. NEXRAD - Wikipedia

    en.wikipedia.org/wiki/NEXRAD

    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 ...

  7. Sutton tube - Wikipedia

    en.wikipedia.org/wiki/Sutton_tube

    Sutton tube. The 5836, a typical reflex klystron used as a low-power microwave source. Note the terminal on the top of the tube, used to power the repeller. Sutton tube was the name given to the first reflex klystron, developed in 1940 by Robert W. Sutton of Signal School group at the Bristol University. The Sutton tube was developed as a local ...

  8. Canadian weather radar network - Wikipedia

    en.wikipedia.org/wiki/Canadian_weather_radar_network

    The Canadian weather radar network consists of 33 weather radars spanning Canada's most populated regions. Their primary purpose is the early detection of precipitation, its motion and the threat it poses to life and property. Each had until 2018 a range of 256 km (159 mi) in radius around the site to detect reflectivity, 3 angles with a range ...

  9. Twystron - Wikipedia

    en.wikipedia.org/wiki/Twystron

    By combining a klystron with a TWT, the result is a relatively compact device with improved bandwidth; typical twystrons have bandwidth up to 15% of the design point. The device was developed by Albert La Rue and Rodney Rubert in the early 1960s and was quickly adopted by many radar designs in order to improve frequency agility and thereby ...
