How should you handle a target with a fluctuating track quality due to sea clutter?

When sea clutter makes a target’s track quality wobble, the priority is to keep a reliable, continuous picture of that target without chasing noise. Reacquiring the target gives ARPA a fresh lock, and re-checking the data confirms you’re still following the same vessel and refreshes the predicted range, bearing, speed, and course. If the track remains unstable, switch to manual tracking for the target so you can directly control and maintain the plot, rather than letting a faulty automatic track drift. Throughout this, preserve separation margins so you can safely maneuver if the target’s path changes unexpectedly. Raising radar gain to “kill” clutter isn’t effective; it tends to amplify noise and clutter as well, which can hide real targets or create false trails. Shutting down ARPA would remove automatic tracking altogether and remove a critical safety layer.
