A radar was built at Mishelevka in Irkutsk on the site of the former, and never operational, Daryal radar which was demolished in 2011. The radar is a Voronezh-VP and is sited close to the former Daryal transmitter building. This radar covers the south and can replace one of the two Dnepr radars at that site.
WINK-TV (channel 11) is a television station licensed to Fort Myers, Florida, United States, serving as the CBS affiliate for Southwest Florida. It is owned by the McBride family and their Fort Myers Broadcasting Company, making it one of a handful of TV stations today to have locally-based ownership.
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.
North Warning System. The North Warning System (NWS, French: Système d'alerte du nord) is a joint United States and Canadian early-warning radar system for the atmospheric air defense of North America. It provides surveillance of airspace from potential incursions or attacks from across North America's polar region.
Doppler effect. The emitted signal toward the car is reflected back with a variation of frequency that depends on the speed away/toward the radar (160 km/h). This is only a component of the real speed (170 km/h). The Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842, is the difference ...
David Knox Barton (September 21, 1927 – February 11, 2023) was an American radar systems engineer who made significant contributions to air defense, missile guidance, monopulse radar, low-altitude tracking, air traffic control, and early warning radar. At age 30, he was the first winner of the David Sarnoff Award in Engineering, for his ...
Radar is a system that uses radio waves to determine the distance ( ranging ), 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.
Innovations include the first Soviet air surveillance radar with a circular scan: the P-8 Volga (NATO: KNIFE REST A) in 1950, the first 3D radar: the 5N69 Salute (NATO: BIG BACK) in 1975, and in 1982 the first VHF-band 3D-radar: the 55Zh6 Nebo (NATO: TALL RACK). Other innovations were radars with frequency hopping; the P-10 Volga A (NATO: KNIFE ...
