The AN/AAR-47 Missile Warning System is a Missile Approach Warning system used on slow moving aircraft such as helicopters and military transport aircraft to notify the pilot of threats and to trigger the aircraft's countermeasures systems.

The AN/AAR-47 is a fielded, combat deployed, electronic warfare system designed to protect aircraft against infrared-guided (IR) missile threats, laser-guided/laser-aided threats, and unguided munitions.

ATK is developing a hostile fire detection capability for the AN/AAR-47A(V)2 system by upgrading the system software (OFP). ATK has demonstrated that the AN/AAR-47 can detect hostile fire for ammunition employing tracers with a miss distances less than 100 m. High Pd demonstrated, greater than 90% against a Gov't provided data set.

The AN/AAR-47 is a passive, missile-approach warning system consisting of four IR sensor assemblies, a central processing unit and a control indicator capable of detecting missile launches from 360 degrees around the aircraft. 2. Requirement. 3. Impacts if Not Funded.

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.

Aug 22, 2019 · • The AN/AAR-47 is a defensive system that warns pilots of missile threats and commands dispensing of flares as an infrared countermeasure. It is composed of a control indicator, a computer processor, and four Integrated Optical Sensor Converters (IOSC). • Since full-rate production in 1987, the sensor has evolved.

The AAR-47(V)2 upgrade has improved UV single-pixel quadrant sensors that eliminated sensor blackening (a known failure mode), increased temperature tolerance, provided a more uniform...

Deployed on helicopters and transport aircraft, the AAR-47 deals with threat missile approach by detecting radiation associated with the rocket motor, letting the crew know that an attacking missile is coming and which direction it’s coming from, and automatically firing decoy flares.

The AN/AAR-47 Missile Warning System is a Missile Approach Warning system used on slow moving aircraft such as helicopters and military transport aircraft to notify the pilot of threats and to trigger the aircraft's countermeasures systems.

The AN/AAR-47, originally fielded in the late 1980s, provides passive warning against infrared and laser guided missiles fired at its host platform.
