Apparatus, method and computer program product for weapon flyout modeling and target damage assessment

Abstract

A weapon flyout simulation method, system, and computer program product, includes modeling a target as a plurality of ellipsoidal zones corresponding to a plurality of zones on the target, and performing hit / miss assessment on the target by determining if said trajectory of the weapon interferes with at least one of said plurality of ellipsoids.

AI Technical Summary

Benefits of technology

[0016]In an exemplary embodiment, the weapon flyout simulation method of the invention may include assessing impact damage on the target. In an exemplary embodiment, the assessing impact damage may be based on at least one of weapon lethality, target survivability, or zone sensitivity of at least one of the plurality of ellipsoidal zones. In an exemplary embodiment, the step of assessing impact damage may include: determining weapon lethality of the weapon; determining effective lethality of the weapon on the target based on the weapon lethality and a zone sensitivity of at least one of the plurality of ellipsoidal zones; and determining if the effective lethality exceeds a survivability threshold of the target.

Problems solved by technology

While modern simulation systems use extremely detailed visual models, these graphics entities are not well suited for mathematically determining whether a projectile of a weapon such as a missile having been fired at a target aircraft has physically hit the target aircraft.

One of the issues associated with performing an accurate assessment of a Hit or Miss engagement on an airborne target, with a missile or ballistic projectile, is the extremely high rate of motion involved in the scenario.

At such rates, the time increment used for digital simulation is far too coarse to accurately assess if an impact has occurred.
