In November 2022, the U.S. approved the sale of 10 Fixed Site-Low, Slow, Small UAV Integrated Defeat Systems (FS-LIDS) to Qatar in a $1 billion deal. A system includes the AN/TPQ-50 counterfire radar and electro-optic cameras to detect and track small UAVs and engages them with EW or interceptors; the sale includes 200 Coyote Block 2s. [13] [21]
Light surface below wing edges is the AN/APQ-181 radar antenna. The AN/APQ-181 is an all-weather, low probability of intercept (LPI) phased array radar system designed by Hughes Aircraft (now Raytheon) for the U.S. Air Force B-2A Spirit bomber aircraft. The system was developed in the mid-1980s and entered service in 1993.
PAVE PAWS Early-warning radar, Alaska. An early-warning radar is any radar system used primarily for the long-range detection of its targets, i.e., allowing defences to be alerted as early as possible before the intruder reaches its target, giving the air defences the maximum time in which to operate.
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 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.
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 APG-63 was developed in the early 1970s and has been operational since 1973, and was installed on all F-15A/Bs. [1] In 1979, it received a major upgrade and became the first airborne radar to incorporate a software programmable signal processor (PSP), and the PSP allowed the system to be modified to accommodate new modes and weapons through software reprogramming rather than by hardware ...
AI.24 Foxhunter radar. Much of the radar system and related operational software was developed at the Radar Research Laboratory of GEC-Marconi Elliott Avionic Systems Ltd., initially at the Elliott Automation plant in Borehamwood, Hertfordshire, United Kingdom, and latterly (from 1981 to 2004) as Marconi Avionics at the (formerly the Xerox site of a matrix of interconnected grey portacabins ...
