Airborne infrared countermeasures systems and method for establishing an infrared communications link between airborne infrared countermeasures systems

During flight, a military aircraft can use an infrared countermeasures (IRCM) system. The IRCM system can use a wide field of view sensor to detect a spectral signature of a missile and record a coarse estimate of the angular location of the missile. Upon such detection, the IRCM system can trigger...

Zusammenfassung:	During flight, a military aircraft can use an infrared countermeasures (IRCM) system. The IRCM system can use a wide field of view sensor to detect a spectral signature of a missile and record a coarse estimate of the angular location of the missile. Upon such detection, the IRCM system can trigger a narrow field of view sensor to more finely determine the angular location of the missile. The narrow field of view sensor can emit infrared light toward the missile, which can confuse the guidance system of the missile and can help redirect the missile away from the aircraft. During time intervals when the narrow field of view sensor is not actively locating a missile, the IRCM system can use the narrow field of view sensor to form an infrared communications link with a corresponding narrow field of view sensor of a corresponding IRCM system of another aircraft.
