Q

The condition known as "glint" refers to a shifting of clutter with each RADAR pulse and can be caused by a:

🔍 Key Concepts

• Marine RADAR signal processing (what each component actually does: MTI, AFC, memory) • Difference between true target motion/clutter and apparent motion caused by equipment issues • How frequency or phase instability between pulses would show up on the display

💭 Think About

• Ask yourself: which of these choices would most directly cause a small, random change in where returns appear from one pulse to the next, without the real targets moving? • Which device or circuit is specifically responsible for keeping the transmitted and received signals stable from pulse to pulse? • Which options would more likely cause total loss/corruption of picture, versus a subtle shift or wander of the clutter?

✅ Before You Answer

• Review what an MTI filter actually removes and how it compares two or more pulses. • Recall the role of AFC (Automatic Frequency Control) in keeping the radar signal stable in frequency/phase from pulse to pulse. • Consider whether interference from electrical equipment usually looks like random streaks/spokes/noise, or like a consistent, pulse-to-pulse positional shift of clutter.
