Line 10:
Infrared guidance systems in heat-seeking missiles are designed to track strong sources of infrared radiation – heat – such as aircraft engines, helping missiles to home in on their targets. IRCM systems are based on a modulated source of infrared radiation with a higher intensity than the target itself. When a [[missile seeker]] observes this modulated radiation, it interferes with or obscures the modulated signal from the aircraft and renders the missile incapable of maintaining a lock on the target.

{{Main article|Directional Infrared Counter Measures}}
Directional IRCM, or [[DIRCM]], allows for a countermeasures laser to be targeted directly at an incoming IR threat. This makes possible a more powerful and effective defense than previous, non-directional infrared countermeasures, as the threat is directly addressed rather than the system essentially painting an area with IR disruption, which results in a weaker signal in any given direction.
