What is the primary purpose of chaff in radar countermeasures?

• A. Generate false target returns
• B. Deny radar scan
• C. Break target tracking modes
• D. Increase radar resolution

Answer: (A)

The main idea is that chaff creates a cloud of radar reflections to confuse the radar by producing many false echoes. When deployed, thin metallic strips reflect radar energy and appear as numerous targets or clutter on the radar screen, making it hard to distinguish the real aircraft from decoys. This degrades tracking reliability and can force the radar to misidentify or lose the real target. Chaff doesn’t shut down radar scans, nor does it improve resolution; those would either be ineffective or work against the purpose, while the goal here is to overwhelm with believable-looking false targets.
