What is target swap in ARPA?

Target swap in ARPA means the automatic tracking system switches its focus from the target you were tracking to a different target. This happens when two targets are close or cross paths, or when the original target’s radar echo becomes weak or obscured, causing the tracker to misidentify and assign its track to another vessel. The effect you’d notice is the tracked target’s data and symbol changing to another target, even though you intended to keep following the original one. This is distinct from simply losing radar updates, changing the display scale, or switching from auto to manual mode, which do not inherently swap the identity of the tracked target.
