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 ...
The facility offers libraries, barbering, handicrafts, education programs, substance-abuse treatment, psychotherapy, and religious services to the inmates.Onsite medical and dental care, provided by mini-clinics in each housing unit, is supplemented by local hospitals and the Duane L. Waters Hospital in Jackson, Michigan.
St. Louis is the site of the former Michigan Chemical Corporation plant, which helped market and produce DDT as a widely commercial product. [8] After its purchase by Velsicol Chemical Corporation , the plant was responsible for a product mixup in the 1970s.
Doppler on Wheels (or DOW) is a fleet of X-band and C-band mobile and quickly-deployable truck-borne radars which are the core instrumentation of the Flexible Array of Radars and Mesonets [1] affiliated with the University of Alabama Huntsville [2] and led by Joshua Wurman, with the funding partially provided by the National Science Foundation ...
Pulse-Doppler signal processing is a radar and CEUS performance enhancement strategy that allows small high-speed objects to be detected in close proximity to large slow moving objects. Detection improvements on the order of 1,000,000:1 are common.
A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. [1] It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has altered the frequency of the returned signal.
In 1956 an AN/FPS-6 replaced the AN/FPS-5 height-finder radar. In 1958 an AN/FPS-20 search radar was deployed at Calumet. By 1961 this radar was upgraded and redesignated as an AN/FPS-64. During 1960 Calumet AFS joined the Semi Automatic Ground Environment (SAGE) system, feeding data to DC-14 at K. I. Sawyer AFB, Michigan.
The radar squadron provided information 24/7 the SAGE Direction Center where it was analyzed to determine range, direction altitude speed and whether or not aircraft were friendly or hostile. Also during 1960 Empire site began operating an AN/FPS-7 radar, and one of the AN/FPS-6 height-finder radars was supplanted by an AN/FPS-26 A in 1963.
