Regarding the FP usage in calibration, which statement is accurate?

• A. They track two unrelated targets
• B. They track two correlated tracks
• C. They both track the same correlated track
• D. They operate independently

Answer: (C)

In calibration, you want a common reference that both processors can judge against. If each FP were chasing a different target, there’d be no shared reference to compare measurements, so you couldn’t reliably estimate biases or alignments. If they operated independently, there’s nothing linking their outputs to identify discrepancies.

The best choice says they both track the same correlated track. That means both FP units are observing and estimating the motion of the same physical target, so their tracks are inherently related through the same underlying state. This shared reference lets you directly compare their measurements and state estimates, revealing any biases, timing offsets, or misalignments between the FPs. The correlation comes from the common target motion, not from separate, unrelated targets.
