🔍 Key Concepts

• Radar controls that affect sensitivity vs. display brightness • How sea clutter and close-range echoes are reduced on radar • Difference between time-related controls and simple gain/brightness controls

💭 Think About

• Ask yourself: which control is specifically designed to reduce very close-range, weak echoes (like from sea return) over a limited distance from the antenna? • Which control acts over time after transmission rather than just making all echoes stronger or weaker? • Which of these choices mainly affects how strong the received signal is, and which mainly affects how bright the screen looks, rather than changing close-range echo behavior?

✅ Before You Answer

• Identify which control is also known as sea clutter or STC and note what range it mainly affects • Separate controls that change overall receiver sensitivity from those that change only near-range sensitivity • Confirm which options only affect display brightness and not the actual radar return strength
