Which function starts tracking new targets in surveillance data processing?

• A. Track initiation
• B. Track processing
• C. Track correlation
• D. Track fusion

Answer: (A)

The main idea here is creating a new track when a novel detection appears. Track initiation is the step where the system sees a detection with no existing track and establishes a new track identity, initializes its state (position, velocity, and uncertainty), and begins monitoring it across subsequent scans. This is how a fresh target begins to be tracked. Track processing is about updating the state of already-established tracks as new measurements come in. Track correlation handles linking measurements to the most likely existing tracks (data association), and track fusion combines track information from multiple sensors into a single, unified track. So none of those start a new track; they deal with what already exists or with combining information from different sources.
