What does IIR stand for?

a global leader in the design and manufacture of thermal imaging infrared cameras.

The imaging infrared version can track a target by locking onto the target's heat source to overcome darkness and inclement weather.

The mid-range munition, or MRM, is a chemical-energy warhead with a dual mode semi-active laser and imaging infrared seeker.

An imaging infrared seeker that can improve the accuracy of the JDAM satellite-guided munitions by more than 200 percent has been tested successfully and is ready for production, said program officials.

The motor and encoder are key components used in the Imaging Infrared (IIR) autonomous terminal seeker and tracker system of the missile.

NCADE also leverages proven imaging infrared seeker components from existing Raytheon production programs, which enables a potentially rapid development and fielding path.

An alternative imaging infrared seeker was developed later for the AGM-142B.
