Q

What circuit controls the suppression of sea clutter?

🔍 Key Concepts

• Sea clutter on radar and what causes it • Purpose of the Sensitivity Time Control (STC) or similar circuits in radar • What each option (EBL, local oscillator, audio amplifier) typically does in a radar set

💭 Think About

• Which radar control is specifically designed to reduce returns from waves and rain close to the ship, without losing targets farther away? • Does sea clutter have more to do with display geometry, signal timing/sensitivity, frequency generation, or audio output? • Think about which circuit works on the RECEIVED echo strength over time after each pulse is transmitted.

✅ Before You Answer

• Match the circuit whose main job is to manage receiver sensitivity vs. time after transmission. • Eliminate options that only affect bearing indication or sound volume, since those do not directly suppress clutter. • Confirm which circuit is associated in manuals with terms like sea clutter, rain clutter, or time-varied gain.
