This video shows how to interpret a displayed vector on the RADAR/ARPA for collision avoidance. It covers the True & Relative vectors when the radar is in Relative motion, Sea Stabilized mode.
True Vector displays the actual movement of a target in relation to a fixed point on Earth. It shows the true course and speed of the target, and it gives a real-world depiction of a vessel’s path over the ground.
Relative Vector represents the movement of a target in relation to the motion of the observing ship or own ship. It shows how the target is moving relative to your own ship’s position and speed. This is useful for collision avoidance, as it indicates how a target’s position changes with respect to your own vessel.
In short, True vector shows a target’s movement over the ground, while Relative vector shows how the target moves relative to your own vessel.
