Q

Which radar control is used to reduce sea return at close ranges?

🔍 Key Concepts

• Difference between sea clutter (near the ship) and rain clutter (farther away) on radar • What each control does: STC, FTC, pulse length, and gain • Which control specifically affects very short ranges close to own ship

💭 Think About

• Which control is designed to reduce echoes from waves very close to your vessel without greatly affecting targets farther away? • Which control mainly affects long-range weak echoes, and which affects short-range strong echoes? • If you were trying to pick out a small target just beyond the sea clutter, which control would you adjust first?

✅ Before You Answer

• Identify which control is also called an anti-sea-clutter or near-range clutter control in some manuals • Confirm which control works by reducing receiver sensitivity for a short time immediately after each transmitted pulse • Make sure you are not confusing the control used for rain clutter with the one used for sea clutter at close range
