(A) study on the weapon target assignment algorithms in decision support system for air defense against area target

Abstract

The focus of this study is to investigate the assignment of weapons to multiple targets in a scenario, specifically when an air defense system is confronted with numerous targets, such as low-altitude rockets or groups of drones. In these engagement scenarios, the accuracy of low-cost weapons in destroying these targets depends heavily on the correct alignment of the launchers with the targets, which can be affected by errors in launcher orientation. Therefore, in solving Weapon Target Assignment (WTA) problems, it is crucial to account for the heading errors created by the launcher's orientation angle. To address this issue, we propose the use of a rotation strategy to align the orientation angle with the target's approach direction can significantly improve the probability of kill (PK) against the target. However, its unitary implementation has limitations, which may result in missed engagements if there is insufficient time to rotate to the desired orientation angle. Thus, as a remedy, we propose an additional WTA method that combines rotation and rotation fix strategy, improving the weakness of losing the opportunity of engagement due to rotation time and heading errors. The efficacy of this approach is evaluated through numerical simulations.
