🔍 Key Concepts

• RADAR main bang / center spot and how different controls affect it • Effect of TUNE vs. STC (Sensitivity Time Control) vs. ACR (Anti‑Clutter Rain) vs. FTE (False Target Elimination) • Relationship between range scale and the appearance of clutter or blank areas near own ship

💭 Think About

• Which control is specifically designed to reduce receiver sensitivity to very close‑in echoes near the center of the display? • As you increase the range scale and the blank spot gets smaller, what does that tell you about whether this is a tuning problem or a time‑based (range‑dependent) filtering problem? • Which of these controls is aimed at suppressing sea/near‑range clutter rather than distant weather or random echoes?

✅ Before You Answer

• Identify which control operates as a time‑varying gain that starts at own ship and changes with range. • Confirm which controls (ACR, FTE) mainly affect distant rain clutter or random false echoes, not just the very center of the display. • Ask: if TUNE were misadjusted, would the center be the only area affected, or would targets across the whole screen degrade?
