Q

How many sequential memory cells with target returns are required to display the target?

🔍 Key Concepts

• Radar target detection versus random noise/clutter • How many consecutive scans (or sweeps) a radar processor typically needs before it treats something as a real target instead of a false echo • The trade‑off between fast detection (fewer memory cells) and reliability (more memory cells)

💭 Think About

• If you only had one memory cell with a return, what problem could that cause when there is sea clutter or rain clutter? • How many consecutive, aligned returns would you expect a radar to require to be reasonably sure a target is real, but still appear quickly on the screen? • Compare what would happen to a weak, intermittent target if the system required a very large number of sequential returns before displaying it.

✅ Before You Answer

• Check which option represents the minimum number of consecutive returns that still gives some protection from single‑scan noise or clutter. • Eliminate any option that would allow single, isolated returns to be displayed as stable targets. • Eliminate any option that would require so many returns that a new target would appear with excessive delay on the display.
