Flight Guard
Flight Guard is an Elta Systems Ltd's brand name for a family of airborne systems for protecting civilian aircraft against man-portable air-defense systems. Description Elta's Flight Guard is a missile detection and avoidance system that is installed on more than 200 military aircraft and helicopters as well as on several VIP commercial aircraft, and has been also installed in aircraft of the El Al, Arkia and Israir fleets that fly to high risk destinations. In September 2003, a year after an attempt was made to shoot down an Arkia Israel Airlines Boeing 757 in Mombasa, Kenya in 2002 (2002 Mombasa attacks), the Israeli Ministry of Transportation selected Elta Systems to perform advanced flight tests of Flight Guard for protecting its commercial aircraft. Part of the funding was used to obtain certification of the system by Israel's Civil Aviation Authority (CAA). The system chosen comprised a radar-based missile approach warning system (MAWS) and countermeasure dispensing syst ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Decoy
A decoy (derived from the Dutch ''de'' ''kooi'', literally "the cage" or possibly ''ende kooi'', " duck cage") is usually a person, device, or event which resembles what an individual or a group might be looking for, but it is only meant to lure them. Decoys have been used for centuries most notably in game hunting, but also in wartime and in the committing or resolving of crimes. Hunting In hunting wildfowl, the term decoy may refer to two distinct devices. One, the duck decoy (structure), is a long cone-shaped wickerwork tunnel installed on a small pond to catch wild ducks. After the ducks settled on the pond, a small, trained dog would herd the birds into the tunnel. The catch was formerly sent to market for food, but now these are used only by ornithologists to catch ducks to be ringed and released. The word ''decoy'', also originally found in English as "coy", derives from the Dutch ''de Kooi'' (the cage) and dates back to the early 17th century, when this type of duck ...

Missile Countermeasures
In military terminology, a missile is a guided airborne ranged weapon capable of self-propelled flight usually by a jet engine or rocket motor. Missiles are thus also called guided missiles or guided rockets (when a previously unguided rocket is made guided). Missiles have five system components: targeting, guidance system, flight system, engine and warhead. Missiles come in types adapted for different purposes: surface-to-surface and air-to-surface missiles (ballistic, cruise, anti-ship, anti-submarine, anti-tank, etc.), surface-to-air missiles (and anti-ballistic), air-to-air missiles, and anti-satellite weapons. Airborne explosive devices without propulsion are referred to as shells if fired by an artillery piece and bombs if dropped by an aircraft. Unguided jet- or rocket-propelled weapons are usually described as rocket artillery. Historically, the word ''missile'' referred to any projectile that is thrown, shot or propelled towards a target; this usage is still recog ...

Directional Infrared Counter Measures
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 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 placed in ...

AN/ALQ-144
The AN/ALQ-144, AN/ALQ-147, and AN/ALQ-157 are US infra-red guided missile countermeasure devices (IRCM). They were developed by Sanders Associates in the 1970s to counter the threat of infra-red guided surface to air missiles like the 9K32 Strela-2. While decoy flares were effective at jamming first generation infra-red guided missiles, each flare was only effective for a short period. If an aircraft needed to loiter over a high risk area or was flying slowly (as helicopters do), it would require a large number of flares to decoy any missile fired at it. The IRCM provided constant protection against infra-red guided missiles. The ALQ-144 and ALQ-147 were first delivered to the US military in 1981. Currently there are over 3,500 in use with the US military, and a total of 6,000 in use by nineteen countries globally. Seven hundred ALQ-157 systems are currently in service. ALQ-144/ALQ-147 Both systems consist of a heated silicon carbide block that radiates a large amount of infra-r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northrop Grumman Guardian
The Northrop Grumman Guardian is a passive anti-missile countermeasure system designed specifically to protect commercial airliners from shoulder-launched missiles (commonly known as MANPADS), using directed infrared countermeasures (DIRCM) technology. According to ''The Wall Street Journal'', the program is now the subject of a lawsuit alleging that "in 2007 and 2008 the company intentionally inflated costs, presented false bills, lied about progress and withheld test data from the Department of Homeland Security." Background The extensive proliferation of MANPADS has resulted in many being available to non-state groups on the international arms black market, sometimes for as little as US$5,000 each. This has resulted in a marked increase of MANPADS attacks on commercial airliners, including the failed 2002 Mombasa airliner attack, the 2003 Baghdad DHL attempted shootdown incident and the 2007 Mogadishu TransAVIAexport Airlines Il-76 crash.

Common Infrared Countermeasures Program
CIRCM, the Common Infrared Countermeasures program, is a United States Army initiative intended to develop a lightweight, low-cost and modular laser-based infrared protection system for U.S. helicopters and light fixed-wing aircraft. The technology will primarily provide defense against shoulder-fired, heat-seeking missiles, or MANPADS. The program is being developed to replace older suites such as the Advanced Threat Infrared Countermeasures (ATIRCM). The CIRCM system will be designed to meet Tri-Service "common" Army, Navy, and Air Force requirements. The Department of Defense’s (DoD) strategy is to competitively develop a lightweight and cost-effective jammer subsystem for installation on all DoD rotary-wing and slow moving fixed-wing aircraft. The Army took delivery of its first CIRCM systems from Northrop Grumman in 2016. Infrared Countermeasures (IRCM) Infrared guidance systems in heat-seeking missiles are designed to track strong sources of infrared radiation – hea ...

Infrared Countermeasures
An infrared countermeasure (IRCM) is a device designed to protect aircraft from infrared homing ("heat seeking") missiles by confusing the missiles' infrared guidance system so that they miss their target ( electronic countermeasure). Heat-seeking missiles were responsible for about 80% of air losses in Operation Desert Storm. The most common method of infrared countermeasure is deploying flares, as the heat produced by the flares creates hundreds of targets for the missile. An infrared sensor that is sensitive to heat, such as emitted from an aircraft engine, is included on missiles launched by man-portable air-defense systems ( MANPADS). Using a steering system, the missile is programmed to home in on the infrared heat signal. Because they are portable, MANPADS missiles have a limited range, burning out a few seconds after launch. Countermeasure systems are usually integrated into the aircraft, such as in the fuselage, wing, or nose of the aircraft, or fixed to an outer ...

Ynetnews
Ynet (stylized as ynet) is one of the major Israeli news and general-content websites, and is the online outlet for the '' Yedioth Ahronot'' newspaper. However, most of Ynet's content is original work, published exclusively on the website and written by an independent staff. History Ynet was launched in June 2000 in Hebrew only; and in 2004 launched its online English edition Ynetnews. In addition, Ynet hosts the online version of Yedioth Aharanot's media group magazines: Laisha (which also operates Ynet's fashion section), Pnai Plus, Blazer, GO magazine, and Mentha. For two years, Ynet had also an Arabic version, which ceased to operate in May 2005. Ynet's main competition comes from Walla! Mako and Nana. Since 2008, Ynet is Israel's most popular internet portal, as measured by Google Trends. In celebration of Israel's independence day in 2005, Ynet conducted a poll to determine whom Ynet readers consider to be the greatest Israelis of all time. The top 200 results were publ ...

Infrared Homing
Infrared homing is a passive weapon guidance system which uses the infrared (IR) light emission from a target to track and follow it seamlessly. Missiles which use infrared seeking are often referred to as "heat-seekers" since infrared is radiated strongly by hot bodies. Many objects such as people, vehicle engines and aircraft generate and emit heat and so are especially visible in the infrared wavelengths of light compared to objects in the background. Infrared seekers are passive devices, which, unlike radar, provide no indication that they are tracking a target. That makes them suitable for sneak attacks during visual encounters or over longer ranges when they are used with a forward looking infrared or similar cuing system. Heat-seekers are extremely effective: 90% of all United States air combat losses over the past 25 years have been caused by infrared-homing missiles. They are, however, subject to a number of simple countermeasures, most notably by dropping flares beh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
