  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. Active electronically scanned array - Wikipedia

    The Eurofighter Typhoon combat aircraft with its nose fairing removed, revealing its Euroradar CAPTOR AESA radar antenna. An active electronically scanned array (AESA) is a type of phased array antenna, which is a computer-controlled antenna array in which the beam of radio waves can be electronically steered to point in different directions without moving the antenna.

  4. Klystron - Wikipedia

    en.wikipedia.org/wiki/Klystron

    400 kW klystron used for spacecraft communication at the Canberra Deep Space Communications Complex. This is a spare in storage. 5 kW klystron tube used as power amplifier in UHF television transmitter, 1952. When installed, the tube projects through holes in the center of the cavity resonators, with the sides of the cavities making contact ...

  5. Airport surveillance radar - Wikipedia

    en.wikipedia.org/wiki/Airport_surveillance_radar

    It is a relocatable, solid-state, all-weather radar with dual-channel, frequency diversity, remote operator controls, and a dual beam tower mounted antenna. The radar provides controllers with range azimuth of aircraft within a 60 nautical mile radius. ASR 8 used a klystron as transmitters power amplifier stage with a load of 79 kV and 40A.

  6. Traveling-wave tube - Wikipedia

    en.wikipedia.org/wiki/Traveling-wave_tube

    Helical waveguides have very nonlinear dispersion and thus are only narrowband (but wider than klystron). A coupled-cavity TWT can achieve 60 kW output power. Operation is similar to that of a klystron, except that coupled-cavity TWTs are designed with attenuation between the slow-wave structure instead of a drift tube. The slow-wave structure ...

  7. AN/SPQ-9 - Wikipedia

    en.wikipedia.org/wiki/AN/SPQ-9

    AN/SPQ-9A (sometimes pronounced as "spook nine") is a United States Navy multi-purpose surface search and fire control radar used with the Mk-86 gun fire-control system (MK86 GFCS). It is a two dimensional surface-search radar, meaning it provides only range and bearing but not elevation. It is intended primarily to detect and track targets at ...

  8. Canadian weather radar network - Wikipedia

    en.wikipedia.org/wiki/Canadian_weather_radar_network

    McGill radar (at the J. S. Marshall Radar Observatory): [11]. 9 metre (30 feet) diameter antenna. Uses a klystron to produce a wavelength signal of 10 cm. (S-Band); Doppler since 1993 and dual polarization was added in 1999.

  9. AN/APQ-120 - Wikipedia

    en.wikipedia.org/wiki/AN/APQ-120

    Aero-13 Fire Control System. The Aero 13 FCR designed for Douglas F4D Skyray is the origin of AN/APQ-120, and it established the configuration of the airborne FCR not only for the radar families of AN/APQ-120, but also a standard for all other airborne radars to follow: Aero 13 FCR was designed as an integrated cylindrical module that could be plugged into the nose of an aircraft, instead of a ...
