Which function handles radar and contact data management?

• A. Radar and contact data management
• B. Weather forecasting
• C. Cargo manifests
• D. Engine diagnostics

Answer: (A)

Radar and contact data management is the function that handles processing radar returns, maintaining the tactical picture, and sustaining accurate contact tracks. It initiates and correlates tracks, updates range, bearing, speed, and course for each contact, and assigns quality flags. It also distributes this contact data to other ship systems such as weapons control and navigation, and supports sensor fusion to keep a coherent, up-to-date picture for decision-making. The other options relate to weather forecasting, cargo logistics, or engine diagnostics, which are separate domains and not involved in managing radar contacts or the tactical picture.
