🔍 Key Concepts

• MTI (Moving Target Indicator) function in marine radar • How MTI affects display of moving vs. stationary targets • Effects of MTI on sea/ground clutter and receiver circuits

💭 Think About

• Ask yourself: What is the main purpose of using MTI on a radar display—what problem is it trying to solve? • Think about what happens to fixed objects (land, buoys, piers) versus ships in motion when MTI is switched on. • Consider whether MTI is primarily changing how the radar receiver amplifies signals over time, or whether it is changing which echoes are allowed to appear on the screen.

✅ Before You Answer

• Verify what MTI does to stationary targets like land and buoys on the display. • Check whether MTI directly controls receiver gain/AGC or mainly affects target selection and clutter suppression. • Confirm how MTI influences the appearance of ground/sea clutter and whether it makes all clutter disappear or just changes how some of it looks.
