Oliktok Long Range Radar Site
Oliktok Long Range Radar Site, DEW station POW-2 or NWS station A-19, is a United States Air Force radar site located east-southeast of Point Barrow, Alaska. The associated military airstrip is known as and is not open for public use. History The site built in 1957 to support the Distant Early Warning Line radar station at Point Barrow (POW-MAIN), which logistically supported it. It was named POW-2 during this period. It was operated by civilian contract workers. DEW Line operations ceased in April 1995, and the personnel were relieved from their duties. The radar station was upgraded with new radars and in 1990 was re-designated part of the North Warning System (NWS) as a Long Range Radar Site, A-19, equipped with a minimally attended AN/FPS-117 long-range surveillance radar. In 1998 Pacific Air Forces initiated "Operation Clean Sweep", in which abandoned Cold War stations in Alaska were remediated and the land restored to its previous state. The site remediation of the rad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

In music or music theory, an eleventh is the Musical note, note eleven scale degrees from the root (chord), root of a chord (music), chord and also the interval (music), interval between the root and the eleventh. The interval can be also described as a Interval (music)#Simple and compound, compound perfect fourth, fourth, spanning an octave plus a fourth. Since there are only seven degrees in a diatonic scale the eleventh degree is the same as the subdominant. The eleventh is considered highly Consonance and dissonance, dissonant with the third (chord), major third. A perfect eleventh is an eleventh which spans exactly 17 semitones.

611th Air Support Group
__NOTOC__ Year 611 ( DCXI) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. The denomination 611 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Persian Empire * Byzantine–Persian War: The Persian army under Shahrbaraz captures Antioch, and most of the remaining Byzantine fortresses in Syria and Mesopotamia. King Khosrau II is re-establishing a neo- Persian Empire, and intensifies his war effort. The Byzantine army, ruined by defeat and corruption, offers only half-hearted opposition. Britain * Cynegils becomes king of the West Saxons, or Wessex, after the death of his uncle Ceolwulf (according to the '' Anglo-Saxon Chronicle'').

Point Barrow, Alaska
Point Barrow or Nuvuk is a headland on the Arctic coast in the U.S. state of Alaska, northeast of Utqiaġvik (formerly Barrow). It is the northernmost point of all the territory of the United States, at , south of the North Pole. (The northernmost point on the North American mainland, Murchison Promontory in Canada, is farther north.) Point Barrow is an important geographical landmark, marking the limit between two marginal seas of the Arctic Ocean, the Chukchi Sea to the west and the Beaufort Sea to the east. It was named by English explorer Frederick William Beechey in 1826 for Sir John Barrow, a statesman and geographer of the British Admiralty. The water around it is normally ice-free for two or three months a year, but this was not the experience of the early explorers. Beechey could not reach it by ship and had to send a ship's boat ahead. In 1826 John Franklin tried to reach it from the east and was blocked by ice. In 1837 Thomas Simpson walked 50 miles west to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Distant Early Warning Line
The Distant Early Warning Line, also known as the DEW Line or Early Warning Line, was a system of radar stations in the northern Arctic region of Canada, with additional stations along the north coast and Aleutian Islands of Alaska (see Project Stretchout and Project Bluegrass), in addition to the Faroe Islands, Greenland, and Iceland. It was set up to detect incoming bombers of the Soviet Union during the Cold War, and provide early warning of any sea-and-land invasion. The DEW Line was the northernmost and most capable of three radar lines in Canada and Alaska. The first of these was the joint Canadian-United States Pinetree Line, which ran from Newfoundland to Vancouver Island just north of the Canada–United States border, but even while it was being built there were concerns that it would not provide enough warning time to launch an effective counterattack. The Mid-Canada Line (MCL) was proposed as an inexpensive solution using bistatic radar. This provided a "trip w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Warning System
The North Warning System (NWS) 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. It replaced the Distant Early Warning Line system in the late 1980s. Overview The NWS consists of both long range AN/FPS-117 and short range AN/FPS-124 surveillance radars, operated and maintained by North American Aerospace Defense Command (NORAD). There are 13 long range sites and 36 short range sites. In Canada, the station sites are owned or leased by the Government of Canada, which also owns most of the infrastructure. The radars and tactical radios are owned by the United States Air Force. The Alaska Regional Operations Control Center (ROCC) at Elmendorf AFB, Alaska controls the stations in Alaska; the Canada East and Canada West Regional Operations Control Centres (ROCCs) at CFB North Bay, Ontario control the ...

Radar Stations Of The United States Air Force
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. The ...
