Temporary radar net, the "five-station radar net" established in 1948; Army Radar Stations, World War II installations of the Aircraft Warning Service with radars (cf. filter centers, Ground Observer Corps stations, etc.) By usage: RBS Express sites, temporary stations for Radar Bomb Scoring trains which had AN/MPS-9 general surveillance radars
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.
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 ...

In 1941, RSS began experimenting with spaced loop direction finders, developed by the Marconi company and the UK National Physical Laboratories. These consisted of two parallel loops 1 to 2 m square on the ends of a rotatable 3 to 8 m beam. The angle of the beam was combined with results from a radiogoniometer to provide a bearing.
