Modeling and Analysis of Target Damage Under the Multi-Posture Projectile and Target Intersection

The distribution characteristics of a warhead fragment field formed by projectile proximity explosion constitute an important factor that affects the damage of spatial target. In this study, the relationship between the warhead fragment spatial parameters and the damaged target was established. Damage efficiency of projectile proximity explosion to target under the intersection condition of multi-posture warhead fragment and damaged target was investigated. Furthermore, by utilizing the relative spatial coordinate transformation relationship between warhead fragment and damaged target a calculation model for damage element hitting damaged target position was established. Moreover, herein the calculation function of the damaged area of the damaged target under different intersection postures was obtained after projectile proximity explosion, and finally the calculation model of the damage probability of the warhead fragment to the damaged target was derived. Through theoretical calculation and experimental analysis, the correlation relationship between the distribution parameters of the warhead fragments and the spatial position coordinates of the damaged target was analyzed. Based on the explosion point and warhead fragment parameters obtained using the multiple screens testing system, and then by using spatial coordinate matrix to carry out the corresponding calculation, the parameters of the system software were provided, the damage results of the target under the follow-up state of projectile proximity explosion were obtained, and the effectiveness and accuracy of the established target damage assessment method were verified.
