Q

Which radar control shortens all echoes on the display and reduces clutter caused by rain or snow?

🔍 Key Concepts

• Difference between sea clutter control (STC) and fast time constant (FTC) on radar • How rain and snow usually appear on a radar screen compared with normal targets • Which control affects overall gain/brilliance versus echo length/shape

💭 Think About

• Ask yourself: Which control is specifically designed to deal with precipitation clutter (rain/snow) rather than waves or general picture brightness? • Think about which control works on the leading edge of an echo pulse to make returns appear shorter and crisper. • Consider: If all echoes (including real targets) appear shortened, which radar function is acting on the time duration of the received pulse rather than just its strength?

✅ Before You Answer

• Verify which control is also called a differentiator in radar theory. • Check your notes on which control is primarily for sea clutter (near the ship) versus rain clutter (farther ranges). • Confirm which control operates on short time intervals to suppress long, smeared returns like rain or snow.
