An electronic countermeasure (ECM) is an electrical or electronic device designed to trick or deceive radar, sonar, or other detection systems, like infrared (IR) or lasers. It may be used both offensively and defensively to deny targeting information to an enemy. The system may make many separate targets appear to the enemy, or make the real target appear to disappear or move about randomly. It is used effectively to protect aircraft from guided missiles. Most air forces use ECM to protect their aircraft from attack. It has also been deployed by military ships and recently on some advanced tanks to fool laser/IR guided missiles. It is frequently coupled with stealth advances so that the ECM systems have an easier job. Offensive ECM often takes the form of jamming. Self-protecting (defensive) ECM includes using blip enhancement and jamming of missile terminal homers.
Barksdale Air Force Base is a United States Air Force (USAF) base in Bossier Parish, Louisiana, in northwest Louisiana. Much of the base is within the city limits of Bossier City, Louisiana, along the base's western and northwestern edge. Barksdale AFB occupies more than 22,000 acres (89 km2) east of Bossier City and along the southern edge of Interstate 20. More than 15,000 active-duty and Air Force Reserve Command (AFRC) members serve at Barksdale.
Radar warning receiver (RWR) systems detect the radio emissions of radar systems. Their primary purpose is to issue a warning when a radar signal that might be a threat is detected, like a fighter aircraft's fire control radar. The warning can then be used, manually or automatically, to evade the detected threat. RWR systems can be installed in all kind of airborne, sea-based, and ground-based assets such as aircraft, ships, automobiles, military bases.
Electronic counter-countermeasures (ECCM) is a part of electronic warfare which includes a variety of practices which attempt to reduce or eliminate the effect of electronic countermeasures (ECM) on electronic sensors aboard vehicles, ships and aircraft and weapons such as missiles. ECCM is also known as electronic protective measures (EPM), chiefly in Europe. In practice, EPM often means resistance to jamming. A more detailed description defines it as the electronic warfare operations taken by a radar to offset the enemy's countermeasure.
The AGM-86 ALCM is an American subsonic air-launched cruise missile (ALCM) built by Boeing and operated by the United States Air Force. This missile was developed to increase the effectiveness and survivability of the Boeing B-52G and B-52H Stratofortress strategic bombers, allowing the aircraft to deliver its payload from a great distance. The missile dilutes an enemy's forces ability to respond and complicates air defense of its territory.
The AN/MPQ-64 Sentinel is an X-band electronically steered pulse-Doppler 3D radar system used to alert and cue Short Range Air Defense (SHORAD) weapons to the locations of hostile targets approaching their front line forces. It is currently produced by Raytheon Missiles & Defense.
The AN/ALR-67 radar warning receiver is designed to warn an aircraft's crew of potentially hostile radar activity. It is an airborne threat warning and countermeasures control system built to be successor to the United States Navy's AN/ALR-45. Northrop Grumman Corporation's Electronic Systems sector was the main contractor for the AN/ALR-67(V) and (V)2. Raytheon Electronic Warfare Systems was the main contractor for the AN/ALR-67(V)3.
The General Dynamics–Grumman EF-111A Raven is a retired electronic-warfare aircraft designed to replace the EB-66 Destroyer in the United States Air Force. Its crews and maintainers often called it the "Spark-Vark", a play on the F-111's "Aardvark" nickname.
An ATSCtuner, often called an ATSC receiver or HDTV tuner, is a type of television tuner that allows reception of digital television (DTV) television channels that use ATSC standards, as transmitted by television stations in North America, parts of Central America, and South Korea. Such tuners are usually integrated into a television set, VCR, digital video recorder (DVR), or set-top box which provides audio/video output connectors of various types.
In the U.S. Air Force, an electronic warfare officer (EWO) is a trained aerial navigator who has received training in enemy threat systems, electronic warfare principles and overcoming enemy air defense systems. These officers are specialists in finding, identifying and countering air defense systems and also radar-, infrared- and optically guided surface-to-air missiles, anti-aircraft artillery as well as enemy fighter planes. In aircraft that could penetrate enemy airspace EWOs protect their aircraft using radar jamming, chaff and flares to deceive potential threats. In other aircraft EWOs work to gather intelligence information on potential enemy air defense systems and communication systems.
The Combat Aircraft Systems Development & Integration Centre (CASDIC) is a laboratory of the Indian Defence Research and Development Organisation (DRDO). Located in Bangalore, Karnataka, India, It is one of the two DRDO laboratories involved in the research and development of airborne electronic warfare and mission avionics systems.
The Boeing B-52 Stratofortress is an American long-range, subsonic, jet-powered strategic bomber. The B-52 was designed and built by Boeing, which has continued to provide support and upgrades. It has been operated by the United States Air Force (USAF) since the 1950s, and NASA for over 50 years. The bomber can carry up to 70,000 pounds (32,000 kg) of weapons and has a typical combat range of around 8,800 miles (14,200 km) without aerial refueling.
A missile approach warningsystem (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.
The AN/MSR-T4 Threat Reaction Analysis Indicator System (TRAINS) is a radar receiver/data processing system to evaluate training performance of attack aircraft crews of the United States Air Force. TRAINS evaluated the crew's Electronic Countermeasures (ECM) against air defense radar by analyzing "the accuracy and effectiveness of inflight ECM performance for combat aircraft ECM pods and internal ECM suite". It captured, recorded, and analyzed transmissions from aircraft responding to threats simulated by the US Dynamics AN/MST-T1 Multiple Threat Emitter Simulator (MUTES) to which the TRAINS was slaved for pointing toward the aircraft. TRAINS data identified the EWO's actions, response times, etc.; and the system included a VHF/UHF receiver and training set.
The ADR-8 was an unguided electronic countermeasures rocket developed by Tracor for use by the United States Air Force. It was used to dispense chaff from Boeing B-52 Stratofortress bombers.
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. In addition 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.
The AR-320 is a 3D early warning radar developed by the UK's Plessey in partnership with US-based ITT-Gilfillan. The system combined the receiver electronics, computer systems and displays of the earlier Plessey AR-3D with a Gilfillan-developed transmitter and planar array antenna from their S320 series. The main advantage over the AR-3D was the ability to shift frequencies to provide a level of frequency agility and thus improve its resistance to jamming.
