It utilized five radar systems located across Oahu. For several weeks, Intercept Center staff had been on high alert because military intelligence had not been able to locate the Imperial Japanese Navy's whereabouts. [2] At 04:00 7 December 1941, USAAC radar plotters arrived to operate radars for their scheduled 04:00 to 07:00 shift.
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 ...
A Royal Air Force Boeing E-3 Sentry over North Yorkshire. An airborne early warning and control (AEW&C) system is an airborne radar early warning system designed to detect aircraft, ships, vehicles, missiles and other incoming projectiles at long ranges, as well as performing command and control of the battlespace in aerial engagements by informing and directing friendly fighter and attack ...
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.

The 1S51M3-2 radar system of the 9K33 Osa TELAR received the NATO codename Land Roll. It was derived from the naval 'Pop Group' radar system but is smaller as it does not require a stabilisation system. An improved system, the Osa-AKM (NATO reporting name SA-8B 'Gecko' Mod 1) was first seen in Germany in 1980. It had improvements to the ...
Most of today's radar detectors detect signals across a variety of wavelength bands: usually X, K, and K a. In Europe the K u band is common as well. The past success of radar detectors was based on the fact that radio-wave beams can not be narrow-enough, so the detector usually senses stray and scattered radiation, giving the driver time to ...
