Up in the air, infrared sensors are called upon for situational awareness. L-3 Cincinnati Electronics (CE) provides high-resolution sensors for the F-35 Joint Strike Fighter (JSF) Electro-Optical Distributed Aperture System (DAS), which provides the pilot warning of hostile fire, missile launch detection, tracking of aircraft, and fire-control capability. Designed by Northrop Grumman, the DAS includes six electro-optical cameras mounted on the surface of the aircraft in various positions to provide a 360-degree, spherical situational awareness system. The imagery is displayed on the pilot’s helmet-mounted display to give a complete view around the aircraft, giving pilots the ability to detect and kill threats from nearly any angle and situation. Once an object is spotted by the DAS, the aircraft’s mission systems can identify it as threat or friend, and the pilot can react accordingly.
