Missile Approach Warning
A missile approach warning system (MAW) is part of the avionics package on some military aircraft. A sensor detects attacking missiles. Its automatic warning cues the pilot to make a defensive maneuver and deploy the available countermeasures to disrupt missile tracking. Guided surface-to-air missile (SAM) systems were developed during World War II and began to make their presence felt in the 1950s. In response, electronic countermeasures (ECM) and flying tactics were developed to overcome them. They proved to be quite successful provided that a reliable and timely threat warning was given. The infrared-seeking missile threat Analysis of aircraft losses due to enemy action since the 1960s shows that at least 70% of all losses were attributed to passive heat seeking i.e. infrared (IR) guided missiles. This might be surprising given that radar guided SAM systems have longer engagement ranges, are faster, have higher maneuvering potential, carry larger warheads and are equipped w ...

A Typhoon F2 Fighter Ignites Its Afterburners Whilst Taking Off From RAF Coningsby MOD 45147957
A, or a, is the first Letter (alphabet), letter and the first vowel letter of the Latin alphabet, used in the modern English alphabet, and others worldwide. Its name in English is ''English alphabet#Letter names, a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version is often written in one of two forms: the double-storey and single-storey . The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English, ''English articles, a'' is the indefinite article, with the alternative form ''an''. Name In English, the name of the letter is the ''long A'' sound, pronounced . Its name in most other languages matches the letter's pronunciation in open syllables. History The earliest know ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pulse-Doppler Radar
A pulse-Doppler radar is a radar system that determines the range to a target using pulse-timing techniques, and uses the Doppler effect of the returned signal to determine the target object's velocity. It combines the features of pulse radars and continuous-wave radars, which were formerly separate due to the complexity of the electronics. The first operational pulse-Doppler radar was in the CIM-10 Bomarc, an American long range supersonic missile powered by ramjet engines, and which was armed with a W40 nuclear weapon to destroy entire formations of attacking enemy aircraft. Pulse-Doppler systems were first widely used on fighter aircraft starting in the 1960s. Earlier radars had used pulse-timing in order to determine range and the angle of the antenna (or similar means) to determine the bearing. However, this only worked when the radar antenna was not pointed down; in that case the reflection off the ground overwhelmed any returns from other objects. As the ground moves at th ...

SAGEM
SAGEM (, translated as "Company of General Applications of Electricity and Mechanics") was a French company involved in defense electronics, consumer electronics, and communication systems. Founded in 1924, SAGEM initially specialised in mechanical engineering and tool manufacture. Early in its existence, it entered the defense sector. The company made a foray into telecommunications in 1942 with the first telex printer, although it was principally a defense-oriented company during the first few decades of the post-war era. This majority focus upon the military sector continued for several years after the departure of Marcel Môme, SAGEM's founder. During the 1980s, SAGEM's distributed Japanese fax machines while developing its own technology. Over the traditional defense sector, such products accounted for a growing share of SAGEM's revenues. During the 1990s, the firm entered the automotive systems sector. Starting in 1997, the company produced GSM telephones for the French ma ...

BAE Systems Electronics, Intelligence & Support
BAE Systems Electronic Systems (ES) is one of three operating groups of BAE Systems Inc., the North American subsidiary of the British global defence contractor BAE Systems PLC. History BAE Systems acquired Lockheed Martin Aerospace Electronic Systems (AES) and Lockheed Martin Control Systems in 2000. BAE Systems Electronic Systems was formed in June 2005 by an internal reorganisation of these businesses. Lockheed had identified AES as a candidate for disposal following a strategic review in 1999. BAE Systems agreed to acquire the group in July and completed its acquisition of AES on 27 November 2000. The group encompassed Sanders Associates, Fairchild Systems and Lockheed Martin Space Electronics & Communications. The purchase of this group by BAE has been described as "precedent setting" given the advanced and classified nature of many of that company's products. In August 2004 BAE acquired Boeing Commercial Electronics for $66 million (£36m). This was an Irving, Texas-base ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Praetorian DASS
The EuroDASS Praetorian DASS is an integral part of Eurofighter Typhoon defensive Aid Sub-System (DASS) providing threat assessment, aircraft protection and support measures in extremely hostile and severe environments. As the DASS is fully integrated, it does not require additional pods that take up weapon stations or would influence the aircraft's aerodynamic performance. The modular nature of the DASS simplifies future upgrades and allows each partner nation or export customer the option to tailor the DASS to their individual needs. History The DASS for the Eurofighter Typhoon The Eurofighter Typhoon is a European multinational twin-engine, supersonic, canard delta wing, multirole fighter. The Typhoon was designed originally as an air-superiority fighter and is manufactured by a consortium of Airbus, BAE Syste ... was intended to be a collaborative effort between the UK, Germany, Spain and Italy.

Solar-blind Technology
Solar-blind technology is a set of technologies to produce images without interference from the Sun. This is done by using wavelengths of ultraviolet light that are totally absorbed by the ozone layer, yet are transmitted in the Earth's atmosphere. Wavelengths from 240 to 280 nm are completely absorbed by the ozone layer. Elements of this technology are ultraviolet light sources, ultraviolet image detectors, and filters that only transmit the range of wavelengths that are blocked by ozone. A system will also have a signal processing system, and a way to display the results (image). Ultraviolet sources Ultraviolet illumination can be produced from longer wavelengths using non-linear optical materials. These can be a second harmonic generator. They must have a suitable birefringence in order to phase match the output frequency doubled UV light. One compound commercially used is L-arginine phosphate monohydrate known as LAP. Research is underway for substances that are very non- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DIRCM
Directional Infrared Counter Measures (DIRCM) are a class of anti-missile systems produced to protect aircraft from infrared homing missiles, primarily MANPADS and similar simple systems. Earlier infrared countermeasures like flares or hot block systems that produce random flashes of IR light are semi- or omnidirectional. This results in the missile seeker receiving relatively little IR energy due to the inverse square law. DIRCM systems instead aim their IR output directly at the missile using some source of tracking information and a trainable emitter. This allows a relatively small device to overwhelm the missile seeker by focusing all of its output on it. Examples are produced by many aerospace companies, such as Aselsan, Leonardo S.p.A., Elbit Systems, Northrop Grumman, ITT Corporation, and BAE Systems. A Russian example is the 101KS-O. Method of operation The systems use an effective method of jamming infrared missile seekers through the sensor aperture and can be ...
