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.).
The most widespread radar device today is undoubtedly the radar gun. This is a small, usually hand-held, Doppler radar that is used to detect the speed of objects, especially trucks and automobiles in regulating traffic, as well as pitched baseballs, runners, or other moving objects in sports. This device can also be used to measure the surface ...
AN/SPS-64 Navigation radar, a surface navigation and search radar, made by Raytheon and used both commercially (brand name Mariner's Pathfinder) and by navies worldwide. [ citation needed ] AN/SPS-65 Development of AN/SPS-58 by Westinghouse as a low altitude radar that is part of the Mark 91 Fire Control System for the Sea Sparrow air defense ...
The Distant Early Warning (DEW) Line, constructed in the late 1950s, was reaching obsolescence in the 1980s.With the signing of North American Air Defence Modernization agreement at the "Shamrock Summit" between Prime Minister Mulroney and President Reagan in Quebec City on 18 March 1985, the DEW Line began its eventual upgrading and transition becoming the North Warning System (NWS) of today.
The former J-31 San Pedro JSS ARSR-1 radar site, California USAF Battle Control System operators monitor the skies from the floor of the program's Eastern Air Defense Sector location. The Joint Surveillance System (JSS) is a joint United States Air Force and Federal Aviation Administration system for the atmospheric air defense of North America.
RaXPol often collaborates with adjacent mobile radar projects, such as Doppler on Wheels and SMART-R. [2] Unlike its counterparts, RaXPol typically places emphasis on temporal resolution, and as such is capable of surveilling the entire local atmosphere in three dimensions in as little as 20 seconds, or a single level in less than 3 seconds.
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 ...
Radar is a system that uses radio waves to determine the distance (), direction (azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method [1] used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.
