Q

How should a radar set be adjusted by the operator to reduce "sea return"?

🔍 Key Concepts

• Sea return (sea clutter) on radar is caused by reflections from nearby waves around your vessel • Difference between gain (overall sensitivity) and STC/sea clutter/suppressor controls on a marine radar • Effect of each control: what happens to targets close to the ship vs far away when you adjust clutter controls

💭 Think About

• Think about which radar control is designed specifically to reduce echoes from waves very close to your vessel, without losing real targets at longer ranges • Consider what happens if you just turn down the gain: how would that affect weak targets far away as well as the sea return near you? • Look at the wording: which option refers to a control that changes sensitivity based on range (time after each pulse)?

✅ Before You Answer

• Identify which control is specifically for sea clutter/sea return, not just overall signal strength • Make sure the chosen control can reduce near-range echoes while still allowing detection of distant weak targets • Confirm that the option you choose matches how STC (Sensitivity Time Control) or a "suppressor" is normally described in your radar manual or study materials
