The Digital Airport Surveillance Radar (DASR) is a newer TRACON radar system, replacing the old analog systems with digital technology. The civilian nomenclature for these radars is the ASR-9 and the ASR-11, and AN/GPN-30 is used by the military. In the ASR-11, two radar systems are included.
Radar coverage along the UK coast, 1939–1940. By 1937, the first three stations were ready, and the associated system was put to the test. The results were encouraging, and the government immediately commissioned construction of 17 additional stations. This became Chain Home, the array of fixed radar towers on the east and south coasts of ...
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.
In 1931, Blumlein invented what he called "binaural sound", now known as stereophonic sound. [2] In early 1931, he and his wife were at the cinema. The sound reproduction systems of the early talkies only had a single set of speakers – the actor might be on one side of the screen, but the voice could come from the other. Blumlein declared to ...
Madrid, Spain, seen from an aerial 16cm satellite image. Carl A. Wiley, [1] a mathematician at Goodyear Aircraft Company in Litchfield Park, Arizona, invented synthetic-aperture radar in June 1951 while working on a correlation guidance system for the Atlas ICBM program. [2]
GL was a rather crude system of limited effectiveness, and this led the Germans to have a dim view of British radar systems. However, an effective system requires more than just the radar; plotting and reporting are equally important, and this part of the system was fully developed in Chain Home.
The MIM-104 Patriot is a mobile interceptor missile surface-to-air missile (SAM) system, the primary such system used by the United States Army and several allied states. It is manufactured by the U.S. defense contractor Raytheon and derives its name from the radar component of the weapon system.
DuBridge later commented, "Radar won the war; the atom bomb ended it." Originally known as "LRN" for Loomis Radio Navigation, LORAN was a proposal of Loomis. It was the most widely used long-range navigation system until the advent of GPS. The system was developed at Rad Lab and is based on a pulsed hyperbolic system.
