Upon publication of a paper in 1939, [21] news of the klystron quickly influenced the work of US and British researchers working on radar technology. Thereafter, klystron equipment was set up in Boston in 1939, and with it, successful blind-landing tests of airplanes were completed. [ 19 ]
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 ...
A gyro-twystron is an amplifier that functions analogously to a twystron, a tube that combines a klystron and a TWT. Like a klystron, it has an input cavity at the upstream end followed by buncher cavities to bunch the electrons, which are followed by a TWT-type slow-wave structure that develops the amplified output signal.
The AN/SPS-49 is a United States Navy two-dimensional, long range air search radar built by Raytheon that can provide contact bearing and range. It is a primary air-search radar for numerous ships in the U.S. fleet and in Spain, Poland, Taiwan aboard Oliver Hazard Perry-class frigates, Canada on its Halifax-class frigate (prior to FELEX mid-life upgrade) and New Zealand on its Anzac-class ...
