SCR-602
The SCR-602 (Set Complete Radio model 602) also known as the AN/TPS-3, was a mobile, lightweight, medium-range, early-warning radar utilized by the United States and its allies during World War II. The radar was originally designed for use during the initial stages of an amphibious assault or military operation where its lightweight relative to other radar systems was a distinct advantage. Once larger radars such as the SCR-270 or AN/TPS-1 came online the SCR-602 could also be used to fill in gaps in radar coverage. Early versions of the SCR-602 were based on the British AMES Type 6, an ''ad-hoc'' system developed by adapting the electronics and antennas from the airborne anti-submarine ASV Mk. II radar. This produced a small and robust radar that could be quickly moved and set up. This proved highly useful in the field and led to requests by the US Army Air Corps for a similar system. The 602 was initially built in Canada while improved versions were being developed in the U ...

AMES Type 6
AMES Type 6, also known as the Light Warning Set or L/W, was a portable early warning radar developed by the Air Ministry Experimental Station (AMES) for use by the Royal Air Force (RAF) in the field. Units in British Army service were officially known as Radar, Anti-Aircraft, Number 4, or AA. No. 4 for short, although this name was rarely used in practice. The system was also built in Canada for use by the US Army, who referred to them as SCR-602-A. The antenna consisted of four Yagi antenna, Yagi antennas mounted on a central pole. Supports running from the pole to the corners of the antennas give it a distinctive hourglass-like shape. The pole sat in a bearing to provide rotation around the vertical axis, allowing it to scan the horizon. The Type 6 was based on the same 1.5 m wavelength electronics as the ASV Mark II radar, ASV Mark II. As this wavelength became increasingly congested, the Type 6 Mark III moved to 212 MHz and introduced a new truck mounting to improve ...

Signal Corps Radio
Signal Corps Radios were U.S. Army military communications components that comprised "sets". Under the Army Nomenclature System, the abbreviation SCR initially designated "Set, Complete Radio", but was later misinterpreted as "Signal Corps Radio." Nomenclature The term SCR was part of a nomenclature system developed for the U.S. Signal Corps, used at least as far back as World War I World War I or the First World War (28 July 1914 – 11 November 1918), also known as the Great War, was a World war, global conflict between two coalitions: the Allies of World War I, Allies (or Entente) and the Central Powers. Fighting to .... Three-letter designators beginning with "SC" were used to denote complete systems, while one and two-letter designators (such as "BC", for basic component, "FT" for mounting, etc.) were used for components. Only a few system designators were used: :::SCM Set, Complete, Meteorological :::SCR Set, Complete, Radio :::SCS Set, Complete, System S ...

Chain Home Low
Chain Home Low (CHL) was the name of a British early warning radar system operated by the RAF during World War II. The name refers to CHL's ability to detect aircraft flying at altitudes below the capabilities of the original Chain Home (CH) radars, where most CHL radars were co-located. CHL could reliably detect aircraft flying as low as . The official name was AMES Type 2, referring to the Air Ministry Experimental Station at Bawdsey Manor where it was developed, but this name was almost never used in practice. The system had originally been developed by the British Army's research group, also based at Bawdsey, as a system for detecting enemy shipping in the English Channel. It was built using the electronics being developed for the aircraft interception radar systems, which worked on the 1.5 m band. This high frequency (200 MHz), for the era, allowed it to use smaller antennas that could be swung back and forth to look for returns, in contrast to the enormous fixed ...

List Of U
A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. A list may be memorialized in any number of ways, including existing only in the mind of the list-maker, but lists are frequently written down on paper, or maintained electronically. Lists are "most frequently a tool", and "one does not ''read'' but only ''uses'' a list: one looks up the relevant information in it, but usually does not need to deal with it as a whole". Lucie Doležalová,The Potential and Limitations of Studying Lists, in Lucie Doležalová, ed., ''The Charm of a List: From the Sumerians to Computerised Data Processing'' (2009). Purpose It has been observed that, with a few exceptions, "the scholarship on lists remains fragmented". David Wallechinsky, a co-author of '' The Book of Lists'', described the attraction of lists as being "because we live in an era of overstimulation, especially in terms of information, and lists help ...

Operation Torch
Operation Torch (8–16 November 1942) was an Allies of World War II, Allied invasion of French North Africa during the Second World War. Torch was a compromise operation that met the British objective of securing victory in North Africa while allowing American armed forces the opportunity to begin their fight against Nazi Germany and Fascist Italy on a limited scale. The French colonies were aligned with Germany via Vichy France but the loyalties of the population were mixed. Reports indicated that they might support the Allies. The American General Dwight D. Eisenhower, supreme commander of the Allied forces in Mediterranean and Middle East theatre of World War II, Mediterranean theater of the war, approved plans for a three-pronged attack on Casablanca (Western), Oran (Centre) and Algiers (Eastern), then a rapid move on Tunis to catch Axis forces in North Africa from the west in conjunction with the British advance from Egypt. The Western Task Force encountered unexpected ...

Identification Friend Or Foe
Identification, friend or foe (IFF) is a combat identification system designed for command and control. It uses a transponder that listens for an ''interrogation'' signal and then sends a ''response'' that identifies the broadcaster. IFF systems usually use radar frequencies, but other electromagnetic frequencies, radio or infrared, may be used. It enables military and civilian air traffic control interrogation systems to identify aircraft, vehicles or forces as friendly, as opposed to neutral or hostile, and to determine their bearing and range from the interrogator. IFF is used by both military and civilian aircraft. IFF was first developed during World War II, with the arrival of radar, and several friendly fire incidents. IFF can only positively identify friendly aircraft or other forces. If an IFF interrogation receives no reply or an invalid reply, the object is not positively identified as foe; friendly forces may not properly reply to IFF for various reasons such as e ...

Kamikaze
, officially , were a part of the Japanese Special Attack Units of military aviators who flew suicide attacks for the Empire of Japan against Allied naval vessels in the closing stages of the Pacific campaign of World War II, intending to destroy warships more effectively than with conventional air attacks. About 3,800 ''kamikaze'' pilots died during the war in attacks that killed more than 7,000 Allied naval personnel, sank several dozen warships, and damaged scores more. The term is used generically in modern warfare for an attacking vehicle, often unmanned, which is itself destroyed when attacking a target; for example, a kamikaze drone. ''Kamikaze'' aircraft were pilot-guided explosive missiles, either purpose-built or converted from conventional aircraft. Pilots would attempt to crash their aircraft into enemy ships in what was called a "body attack" (''tai-atari'') in aircraft loaded with bombs, torpedoes or other explosives. About 19 percent of ''kamikaze'' attacks ...

A-scope
A radar display is an electronic device that presents radar data to the operator. The radar system transmits pulses or continuous waves of electromagnetic radiation, a small portion of which backscatter off targets (intended or otherwise) and return to the radar system. The receiver converts all received electromagnetic radiation into a continuous electronic analog signal of varying (or oscillating) voltage that can be converted then to a screen display. Modern systems typically use some sort of raster scan display to produce a map-like image. Early in radar development, however, numerous circumstances made such displays difficult to produce. People developed several different display types. Oscilloscopes Early radar displays used adapted oscilloscopes with various inputs. An oscilloscope generally receives three ''channels'' of varying (or oscillating) voltage as input and displays this information on a cathode ray tube. The oscilloscope amplifies the input voltages and sends ...
