Chaff is designed to jam which systems?

• A. Ground Controlled Radar Installation Or Radar Controlled Missiles
• B. Infrared Imaging Sensors
• C. Naval Sonar Arrays
• D. Satellite Communication Links

Answer: (A)

Chaff is a radar countermeasure: it disperses many small, highly reflective flakes or fibers to create a cloud of radar echoes. This flood of echoes fools radar systems by generating decoys and clutter, making it hard for the radar to distinguish the real aircraft and to maintain an accurate track. That’s why its primary role is against radar-based targets such as ground-controlled radar installations and radar-guided missiles. Infrared imaging sensors detect heat, not radio waves, so chaff doesn’t affect them. Naval sonar arrays and satellite communication links rely on sound or directed RF links rather than broad RF reflections in the same way, so chaff isn’t designed to jam those systems.
