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 ...
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.
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 ...
During the modernization program of Canadian weather radar network, it is being replaced again on the same site in the spring of 2021 by an S band and dual-polarization radar with an estimated construction date from March to June. [3] This new radar uses a klystron, instead of a magnetron, and has: [7] [8] Frequency : 2.7 - 2.9 GHz
The ASR-9 was the first airport surveillance radar to detect weather and aircraft with the same beam and be able to display them on the same screen. It has a digital Moving Target Detection (MTD) processor which uses doppler radar and a clutter map giving advanced ability to eliminate ground and weather clutter and track targets. It is ...
Weather radar in Norman, Oklahoma with rainshaft Weather (WF44) radar dish University of Oklahoma OU-PRIME C-band, polarimetric, weather radar during construction. Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.).
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 ...
The klystron, a microwave tube, [20] was noticed in 1938 by Sperry Gyroscope, who gave the Varian brothers and Hansen a contract to do further work. [17] 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]
