TPS-43 Air Force S-Band Tactical Surveillance Radar, Westinghouse - National Electronics Museum - DS
The AN/TPS-43 is a transportable air search 3D radar produced in the United States originally by Westinghouse Defense and Electronic Division, which was later purchased by Northrop-Grumman. It is used primarily for early warning and tactical control, often for control over an associated surface-to-air missile battery or airfield. It is designed to be transported in two M35 cargo trucks and easily air-transportable on two pallets. The TPS-43 uses multiple feed horns and an organ-pipe scanner to rapidly scan its pencil beam vertically while the entire antenna system rotates to scan in azimuth. By comparing the relative power of a return in one or more of the vertical feed horns, the target altitude can be determined. Since its introduction in 1966 it has undergone many modifications. In later versions, the organ-pipe was replaced by a stripline matrix to produce beamforming that had the same output pattern but had no moving parts. Many more upgrades were made to the transmi ...

Falklands War
The Falklands War ( es, link=no, Guerra de las Malvinas) was a ten-week undeclared war between Argentina and the United Kingdom in 1982 over two British dependent territories in the South Atlantic: the Falkland Islands and its territorial dependency, South Georgia and the South Sandwich Islands. The conflict began on 2 April, when Argentina invaded and occupied the Falkland Islands, followed by the invasion of South Georgia the next day. On 5 April, the British government dispatched a naval task force to engage the Argentine Navy and Air Force before making an amphibious assault on the islands. The conflict lasted 74 days and ended with an Argentine surrender on 14 June, returning the islands to British control. In total, 649 Argentine military personnel, 255 British military personnel, and three Falkland Islanders were killed during the hostilities. The conflict was a major episode in the protracted dispute over the territories' sovereignt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pulse Repetition Frequency
The pulse repetition frequency (PRF) is the number of pulses of a repeating signal in a specific time unit. The term is used within a number of technical disciplines, notably radar. In radar, a radio signal of a particular carrier frequency is turned on and off; the term "frequency" refers to the carrier, while the PRF refers to the number of switches. Both are measured in terms of cycle per second, or hertz. The PRF is normally much lower than the frequency. For instance, a typical World War II radar like the Type 7 GCI radar had a basic carrier frequency of 209 MHz (209 million cycles per second) and a PRF of 300 or 500 pulses per second. A related measure is the pulse width, the amount of time the transmitter is turned on during each pulse. After producing a brief pulse of radio signal, the transmitter is turned off in order for the receiver units to hear the reflections of that signal off distant targets. Since the radio signal has to travel out to the target and back ag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bangladesh Air Force
The Bangladesh Air Force (BAF) ( bn, বাংলাদেশ বিমান বাহিনী, Bangladesh Biman Bahini) is the aerial warfare branch of the Bangladesh Armed Forces. The Air Force is primarily responsible for air defence of Bangladesh's sovereign territory as well as providing air support to the Bangladesh Army and Bangladesh Navy. Furthermore, the BAF has a territorial role in providing tactical and strategic air transport and logistics capability for the country. Since its establishment on 28 September 1971, the Air Force has been involved in various combat and humanitarian operations, from the Bangladesh Liberation War in which it was born, to supporting international efforts including United Nations peacekeeping missions. Operation Kilo Flight was a famous operation conducted by the Bangladesh Air Force during the Bangladesh Liberation War. History Foundation The Bangladesh Air Force was officially formed on 28 September 1971 consisting of the revolt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Río Grande, Tierra Del Fuego
Río Grande is a city in Argentina, on the north coast of the eastern part of the Isla Grande de Tierra del Fuego. It has a population of 67,038, and is the industrial capital of the Tierra del Fuego Province, Argentina, Tierra del Fuego Province. It is located north-east of Ushuaia, the capital of the province. It is served by Hermes Quijada International Airport. History Sheep farming, as many other places in Patagonia, was the main impetus for population settlements beginning in the late 19th century. Abundant rivers, the seacoast, and good pastures were some of the reasons that fueled population growth. Río Grande was founded on July 11, 1921, when the central government issued a decree recognising this locality as the "Agricultural Colony of Río Grande". In the beginning, the land was subdivided among a few families, owning large estates until the agrarian reform of 1925. Cattle raising became one of the most important economic activities in the area. In 2014, the ci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RAF Buchan
Royal Air Force Buchan or more simply RAF Buchan is a former Royal Air Force station near Peterhead in Aberdeenshire, Scotland. Buchan opened in 1952 as a radar centre in the ROTOR radar network. It was soon upgraded with the installation of the powerful AMES Type 80 radar, and became a Master Radar Station, directing most air defence activities directly from its radar displays. During the upgrades to the Linesman/Mediator network it was planned to close, but its location and support for air traffic control kept it operational with its Type 80 through this era. In 1991, Buchan became one of two locations to host a Control and Reporting Centre (CRC) of the new Improved United Kingdom Air Defence Ground Environment that replaced Linesman. As part of this upgrade, it received an AMES Type 92 radar although its Type 80 continued operations for some time before finally shutting down in 1993 along with its associated Sperry TPS-34 height finders. The CRC was hosted in a double-stor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stanley, Falkland Islands
Stanley (; also known as Port Stanley) is the capital city of the Falkland Islands. It is located on the island of East Falkland, on a north-facing slope in one of the wettest parts of the islands. At the 2016 census, the city had a population of 2,460. The entire population of the Falkland Islands was 3,398 on Census Day on 9 October 2016. Stanley is represented by five of the eight elected members of the Legislative Assembly of the Falkland Islands, Stacy Bragger, Barry Elsby, Mark Pollard, Roger Spink and Leona Vidal Roberts. An elected Town Council of Stanley existed from 1948 to 1973. On 20 May 2022, it was announced that, as part of the Platinum Jubilee Civic Honours, Stanley would receive city status.

AN/TPS-75
The AN/TPS-75 is a transportable passive electronically scanned array air search 3D radar produced in the United States. It was originally designated the TPS-43E2. Although the antenna is a radically new design from the TPS-43, the radar van itself, which houses the transmitter, receiver processors, and displays is very similar to the older TPS-43E2. It is produced in the United States originally by Westinghouse Defense and Electronic Division, which was later purchased by Northrop-Grumman. Description The AN/TPS-75 is the primary transportable Aerospace Control And Warning (AC&W) radar used by the United States Air Force.The US Military description for radar type TPS is "Ground, Transportable; Radar; Detecting, Range and Bearing, Search". The TPS-75 is capable of transmitting 5-Megawatts of power. (Although 5-Megawatts is almost never achieved; realistically it is approx 2.8 Megawatts) This radar was developed as an upgrade of the AN/TPS-43(V), which entered US service in 1 ...

Phased Array Antenna
In antenna theory, a phased array usually means an electronically scanned array, a computer-controlled array of antennas which creates a beam of radio waves that can be electronically steered to point in different directions without moving the antennas. In a simple array antenna, the radio frequency current from the transmitter is fed to multiple individual antenna elements with the proper phase relationship so that the radio waves from the separate elements combine ( superpose) to form beams, to increase power radiated in desired directions and suppress radiation in undesired directions. In a phased array, the power from the transmitter is fed to the radiating elements through devices called ''phase shifters'', controlled by a computer system, which can alter the phase or signal delay electronically, thus steering the beam of radio waves to a different direction. Since the size of an antenna array must extend many wavelengths to achieve the high gain needed for narrow bea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shaped Reflector
A parabolic antenna is an antenna that uses a parabolic reflector, a curved surface with the cross-sectional shape of a parabola, to direct the radio waves. The most common form is shaped like a dish and is popularly called a dish antenna or parabolic dish. The main advantage of a parabolic antenna is that it has high directivity. It functions similarly to a searchlight or flashlight reflector to direct radio waves in a narrow beam, or receive radio waves from one particular direction only. Parabolic antennas have some of the highest gains, meaning that they can produce the narrowest beamwidths, of any antenna type. In order to achieve narrow beamwidths, the parabolic reflector must be much larger than the wavelength of the radio waves used, so parabolic antennas are used in the high frequency part of the radio spectrum, at UHF and microwave ( SHF) frequencies, at which the wavelengths are small enough that conveniently-sized reflectors can be used. Parabolic antennas are used a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
