In radar tracking, how is a new track created?

• A. By the radar automatically solving optimization for existing tracks.
• B. Track initiation detects clusters of measurements and creates new tracks.
• C. Track maintenance validates a track after corroborative measurements.
• D. Track confirmation deletes tentative tracks.

Answer: (B)

Track initiation is the moment a new target is formed from measurements that don’t fit any existing track. When a burst of detections arrives that cannot be associated with current tracks, the system looks for a cluster of unassociated measurements in a given time window. If those measurements appear to come from the same object, a new track is started for that cluster, typically as a tentative track that will receive more corroborating measurements to become established. This is why this option is the best: it specifically describes creating a new track from clustered, unassigned measurements rather than modifying existing tracks or handling maintenance or confirmation procedures. The other activities relate to existing tracks rather than creating new ones: optimization deals with fitting measurements to current tracks, track maintenance checks ongoing validity, and track confirmation moves a tentative track toward a confirmed state after enough corroborating data.
