🔍 Key Concepts

• RADAR clutter controls such as sea clutter/sea return and rain clutter • How small waves and swell near your vessel affect the RADAR display • Difference between a true target echo and background reflections

💭 Think About

• Ask yourself: Does sea return usually come from other vessels/objects, or from the sea surface itself? • Think about what you adjust with the "sea" or "STC" (sensitivity time control) knob on a RADAR—what kind of unwanted echoes is that trying to reduce? • Which option best describes an unwanted background effect that can mask real targets near your own ship?

✅ Before You Answer

• Make sure the option you choose clearly involves reflections from the sea surface, not just any target at sea. • Eliminate any choice that sounds like a mechanical fault (e.g., water intrusion) rather than a RADAR display phenomenon. • Confirm that the description matches something you would normally remove by adjusting sea clutter controls on the RADAR.
