Clutter is unwanted radar returns. Name two common clutter types.

• A. Electronic bias and flicker noise
• B. Ground/sea clutter and weather clutter (precipitation)
• C. Target returns and false alarms
• D. Thermal noise and shot noise

Answer: (B)

Clutter is unwanted radar returns from things other than your target. Two common clutter types are ground/sea clutter and weather clutter (precipitation). Ground clutter comes from reflections off terrain features like buildings, trees, and hills, while sea clutter comes from the rough ocean surface. Weather clutter arises from precipitation such as rain, snow, or hail, which can produce strong, widespread echoes. These are typical because they are external environmental reflections that can mimic or mask real targets, unlike internal instrument noise (electronic bias, flicker, thermal, shot noise) or actual target returns.
