The digits of numeric sample case identifiers specify following propNav modeling options:
  • 1000's digit - Missile type; 1 = SAM, 2 = AAM
  • 100's digit - Proportional Navigation (PN) guidance method;
    1. True PN (TPN); AAM cases used TPN with guidance command preservation
    2. Pure PN (PPN)
    3. Zero Effort Miss (ZEM) PN
    4. Augmented True PN (ATPN)
    5. Augmented Pure PN (APPN)
    6. Augmented Zero Effort Miss (AZEM) PN
  • 10's digit - Proportional Navigation constant
  • 1's digit - Target turning acceleration in g's
