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.
Pod-mounted active Electronic countermeasure system, upgraded from AN/ALQ-119: F-4G Phantom II, F-16 Fighting Falcon: Raytheon: AN/ALQ-187: Electronic countermeasure, part of the ASPIS system: F-16 Fighting Falcon: AN/ALQ-196: Integrated defensive Electronic countermeasure system: AC-130U Spooky II, MC-130E Combat Talon: BAE Systems: AN/ALQ-202
Examples of electronic counter-countermeasures include the American Big Crow program, which served as a Bear bomber and a standoff jammer. [6] It was a modified Air Force NKC-135A and was built to provide capability and flexibility of conducting varied and precision electronic warfare experiments. [7]
Radar jamming and deception is a form of electronic countermeasures (ECMs) that intentionally sends out radio frequency signals to interfere with the operation of radar by saturating its receiver with noise or false information.
The AN/ALE-50 towed decoy system is an electronic countermeasure tool designed by Raytheon to protect multiple US military aircraft from air-to-air and surface-to-air radar-guided missiles. [1] The AN/ALE-50 towed decoy system is an anti-missile countermeasures decoy system used on U.S. Air Force , Navy , and Marine Corps aircraft, and by ...
Electronic warfare self-protection (EWSP) is a suite of countermeasure systems fitted primarily to aircraft for the purpose of protecting the host from weapons fire and can include, among others: directional infrared countermeasures (DIRCM, flare systems and other forms of infrared countermeasures for protection against infrared missiles; chaff ...
IED Countermeasure Equipment (ICE): In the fall of 2004, the Army Research Laboratory (ARL) at White Sands Missile Range in New Mexico and New Mexico State University's Physical Science Laboratory developed a jamming system that uses low-power radio frequency energy to block the radio signals that detonate enemy IEDs.
First developed in the early 1960s, [3] [5] the ALR-20 began appearing on B-52D bombers (before 1967) [6] and B-52Gs in 1967-1969. [7] [8] In accordance with the Joint Electronics Type Designation System (JETDS), the "AN/ALR-20" designation represents the 20th design of an Army-Navy electronic device for passive countermeasures signal receiver.
