What is the target tracking method used by the Stinger round?

• A. IR and UV
• B. Radar-based tracking
• C. Infrared only
• D. Ultraviolet only

Answer: (A)

Stinger’s target tracking relies on a two-spectral-band seeker that uses both infrared and ultraviolet signals. The infrared channel locks onto the heat signature of the aircraft—the hot engine exhaust and surrounding airframe—providing a strong, high-contrast image against cooler background skies. The ultraviolet channel adds a distinct signature that helps verify the target and discriminate it from background clutter or decoys, especially in challenging lighting or cluttered environments. By fusing information from both bands, the system can maintain a reliable lock as the target maneuvers and as countermeasures try to spoof one channel. Radar-based tracking isn’t involved here, since this is a passive, heat-seeking system, and relying on infrared alone would be more vulnerable to background noise, while ultraviolet alone would be less reliable in some conditions.
