A VTS system integrates data from multiple sensors to create a comprehensive traffic image. It receives a radar plot for a target and, simultaneously, an AIS transmission with a matching position but a conflicting course and speed. How should a modern, integrated VTS system typically handle this conflicting information?

1. Automatically delete both targets to avoid confusion.
2. Prioritize the AIS data as it is self-reported by the vessel.
3. Display both targets separately, requiring manual operator correlation.
4. Fuse the data into a single track but flag it for operator attention and verification.
