TPS-1B Radar
The AN/TPS-1 Radar was an early warning and tactical control radar developed by Bell Labs and the MIT Radiation Laboratory during World War II. Initially used by the US Army, it was later used by the United States Air Force Air Defense Command, and a number of European armed forces. A number of variations were produced by several vendors, including Western Electric, Westinghouse Electric, Bendix Corporation and several European manufacturers in the post-war era. In Royal Air Force service it was known as AMES Type 61. The TPS-1 is a lightweight portable search radar using a cut-down parabolic antenna of the "orange peel" design with an off-axis feed and transmitting in the L-band between 1220 and 1280 megahertz (MHz). The initial versions were designed to break down into ten packages and then be assembled on-site, but a number of adaptations to large trucks and even school bus frames were made over the years. A crew of two could operate the radar. The 1B model could detect bomb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
L-band
The L band is the Institute of Electrical and Electronics Engineers (IEEE) designation for the range of frequencies in the radio spectrum from 1 to 2 gigahertz (GHz). This is at the top end of the ultra high frequency (UHF) band, at the lower end of the microwave range. Applications Mobile service In Europe, the Electronic Communications Committee (ECC) of the European Conference of Postal and Telecommunications Administrations (CEPT) has harmonized part of the L band (1452–1492 MHz), allowing individual countries to adopt this spectrum for terrestrial mobile/fixed communications networks supplemental downlink (MFCN SDL). By means of carrier aggregation, an LTE-Advanced or UMTS/HSDPA base station could use this spectrum to provide additional bandwidth for communications from the base station to the mobile device; i.e., in the downlink direction. In the Americas, mobile services are operated between the 1.7 GHz to 2.1 GHz range in the PCS and AWS bands. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iwo Jima
Iwo Jima (, also ), known in Japan as , is one of the Japanese Volcano Islands and lies south of the Bonin Islands. Together with other islands, they form the Ogasawara Archipelago. The highest point of Iwo Jima is Mount Suribachi at high. Although south of the metropolis of Tokyo on the mainland, this island of 21 km2 (8 square miles) is administered as part of the Ogasawara Subprefecture of Tokyo. Since July 1944, when all the civilians were forcibly evacuated, the island has had a military-only population. The island was the location of the Battle of Iwo Jima between February 1945 and March 1945. This engagement saw some of the fiercest fighting of the Pacific War, with each side suffering over 20,000 casualties in the battle. The island became globally recognized when Joe Rosenthal, of the Associated Press, published his photograph '' Raising the Flag on Iwo Jima'', taken on Mount Suribachi. The US military occupied Iwo Jima until 1968, when it was returned to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II Radars
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In ''scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radars 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 t ...

Military Radars Of The United States
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's military may f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Target Allocation Radar TPS-1E
The Target allocation radar TPS-1E (German:Zielzuweisungsradar TPS-1E (ZZR)) is an omnidirectional pulse radar device. It was used from 1958 until 1989 by the Swiss Air Force. It was also used by German army (''Heer'') air defence reconnaissance platoons up until the early 1990s. History TPS-1E was ordered in the late 1950s for the heavy antiaircraft units. Target data were transmitted by telephone or radio to anti-aircraft artillery batteries. In the radar equipped batteries with the Fire control radar Mark VII, the Parallax computer Meta converted the data to local coordinates. In the remaining heavy antiaircraft radar batteries, data were used in manual targeting. In the middle of 1963 the ZZR was used together with the new Air Defence Operations Center 63 for the same task. After the introduction of fire control unit 75, Skyguard ZZR was incorporated in the new mobile radar units. It was used until the introduction of the TAFLIR systems in 1989.

Nike Missile
The United States Army's Nike Ajax was the world's first operational guided surface-to-air missile (SAM), entering service in 1954. Nike Ajax was designed to attack conventional bomber aircraft flying at high subsonic speeds and altitudes above . Nike was initially deployed in the US to provide defense against Soviet bomber attacks, and was later deployed overseas to protect US bases, as well as being sold to various allied forces. Some examples remained in use until the 1970s. Originally known simply as Nike, it gained the Ajax as part of a 1956 renaming effort that resulted from the introduction of Hercules. It was initially given the identifier SAM-A-7 (Surface-to-air, Army, design 7) as part of an early tri-service identification system, but later changed to MIM-3 (Mobile Interceptor Missile, design 3) in 1962.Nike was initially designated SAM-G-7, and later changed to SAM-A-7.

Lashup Radar Network
The Lashup Radar Network was a United States Cold War radar netting system for air defense surveillance which followed the post-World War II "five-station radar net" and preceded the "high Priority Permanent System". ROTOR was a similar expedient system in the United Kingdom. Background United States electronic attack warning began with a 1939 networking demonstration at Twin Lights station NJ, and 2 SCR-270 radar stations during the August 1940 " Watertown maneuvers" (NY). When "Pearl Harbor was attacked, here were 8 CONUSearly-warning stations" (ME, NJ, & 6 in CA), and Oahu's Opana Mobile Radar Station had 1 of 6 SCR-270s. CONUS "Army Radar Station" deployments for World War II were primarily for coastal anti-aircraft defense, e.g., L-1 at Oceanside CA, J-23 at Seaside OR (Tillamook Head), and B-30 at Lompoc CA; and "the AAF...inactivated the aircraft warning network in April 1944." In 1946 the Distant Early Warning Line was "first conceived—and rejected". By 1948 there ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
