What processor function attempts to correlate plots to existing tracks?

• A. Track Processor
• B. Data Processor
• C. Signal Processor
• D. Target Processor

Answer: (A)

Matching new radar plots with current targets is track maintenance. The track processor keeps the active set of tracks, uses a motion model to predict where each target should be, and then tests incoming plots to see which track they belong to. This correlation uses gating—checking if a plot falls within the predicted area of a track—and if it does, the plot is linked to that track and the track’s state is updated accordingly. If no existing track matches, a new track may be created, or a plot may be discarded if it’s not usable. The other processors handle different parts of the radar system: the signal processor manages the raw signal processing and detection, the data processor handles data formatting and flow, and the target processor deals with higher-level target information rather than tying plots to tracks.
