What is vector plotting in ARPA and its purpose?

Vector plotting in ARPA is the automatic projection of a target’s future positions by extending its current speed and course on the radar display. This creates vectors that show where the target is likely to be at future times, allowing the system to calculate the closest point of approach and the time to that point relative to your vessel. The purpose is to reveal collision risk early and to support safe maneuver decisions, such as when to alter course or speed. This feature isn’t about measuring a target’s height or color, predicting weather, or calculating your own speed in isolation.
