Infrared countermeasures can affect the seeker by?

• A. They degrade tracking accuracy over several minutes
• B. They cause immediate system shutdown
• C. They permanently disable seekers
• D. Flares and decoys can temporarily mislead the seeker or degrade tracking accuracy.

Answer: (D)

Infrared countermeasures affect the seeker by creating competing infrared signatures that confuse the tracking system. Flares and decoys emit strong heat signatures that the seeker often interprets as the hottest or most relevant target. When the seeker locks onto the decoy, it can lose the real target or have its tracking degraded, and this effect is temporary. Once the decoy fades or the seeker reacquires the target, tracking can resume. These measures are designed to mislead momentarily, not to shut down or permanently disable the seeker.
