VMTI Field Dependencies

This semantic rule validates MISB ST 0903 dependency checks between target counts, frame dimensions, references, and tracker timestamps.

What This Test Does​

The rule checks relationships such as:

  • Tag 6 NumTargetsReported matching the number of Tag 101 target series items
  • Tag 6 not exceeding Tag 5 TotalNumTargetsDetected
  • pixel-space target fields requiring both Tag 8 FrameWidth and Tag 9 FrameHeight
  • target and tracker algorithm references matching top-level algorithm definitions
  • object and feature ontology references matching top-level ontology definitions
  • tracker latest-observation time not moving before tracker first-observation time

✅ Pass Criteria​

The test passes when all detected MISB ST 0903 VMTI local sets satisfy the required internal consistency checks.

❌ Fail Criteria​

The test fails when any target count, reference, frame-dimension dependency, or tracker time relationship is inconsistent.
