What does a persistent echo that moves with your trend indicate?

• A. A stationary object.
• B. A real moving target that may require tracking or monitoring.
• C. Sea clutter.
• D. Noise.

Answer: (B)

A persistent echo that moves with your trend points to a real moving target rather than background clutter or random noise. Because the echo remains in view across multiple radar sweeps and tracks in a way that mirrors your vessel’s own motion, it indicates an actual object with its own velocity. That’s something you’d want to monitor or track to assess potential risk or to determine a safe course of action. If the echo were a stationary object, it wouldn’t follow your trend as you move, and it would appear fixed relative to the ground rather than moving coherently with your ship. Sea clutter tends to be diffuse, variable, and tied to waves and sea state, not to a steady, trackable motion. Noise is random and intermittent, not a persistent, trackable signal.
