Abstract:
1. A directed infrared countermeasures (DIRCM) system for use on an aircraft to track and jam a missile having an infrared (IR) missile seeker, comprising: a pointer-tracker having a detector and a Roll/Nod gimbal that includes optics for collecting incident IR radiation and routing it to the detector and an JR laser transmitter mounted thereon; an JR laser optically coupled to the laser transmitter; and a missile warner including a receiver that detects a likely missile launch and passes the threat coordinates to the pointer-tracker, said pointer-tracker slewing the gimbal to the threat coordinates to initiate tracking and then processing the data from its detector to refine tracking of and verify the threat, and, if verified, engage the IR laser to emit a modulated IR laser beam through the laser transmitter to jam the IR missile seeker.
