Which statement correctly compares IR Target Adaptive Guidance and NUV Target Adaptive Guidance?

• A. IR Target Adaptive Guidance steers forward of heat source; NUV Target Adaptive Guidance steers from nose to main body.
• B. IR Target Adaptive Guidance steers from nose to main body; NUV Target Adaptive Guidance steers forward of heat source.
• C. IR Target Adaptive Guidance and NUV Target Adaptive Guidance both steer in the same way.
• D. IR Target Adaptive Guidance is unrelated to heat sources.

Answer: (A)

Target Adaptive Guidance describes how the missile uses its seeker signal to steer toward a target, and the reference point it uses for guiding is different between infrared and near-UV modes. In infrared Target Adaptive Guidance, the seeker locks onto the heat source on the target. The guidance then steers ahead of that hot spot to anticipate the target’s motion and the missile’s own response time. That forward-leading behavior helps ensure the missile can intercept even if the target maneuvers. In near-UV Target Adaptive Guidance, the seeker uses the UV signature of the target in a different way, guiding from the nose toward the main body of the aircraft rather than leading ahead of a heat source. This approach centers the guidance on the target’s overall UV profile, not the forward heat cue. So the infrared mode leads the heat source, while the near-UV mode steers from the nose to the main body. The other statements don’t fit because they either misstate the reference points or claim the two modes behave identically, or ignore the relation to heat sources.
