Abstract

To improve the target damage efficiency under projectile proximity, this paper utilizes light field imaging method to establish projectile proximity position parameters and warhead fragment spatial position testing model, studies the correlation calculation method between warhead fragment and the damaged target. The calculation principle of warhead fragment spatial position is established in the intersection of two light field cameras, combines acquired warhead fragment spatial position parameters to give the distribution characteristics of the warhead fragment field, and the dynamic dispersion velocity of the warhead fragment field, obtains the calculation model of spatial warhead fragment kinetic energy, derives the target damage efficiency evaluation function of multiple warhead fragments penetrating the target by synthesizing warhead fragment s vector velocity and target damage area and warhead fragment mass. Through calculation and analysis, the results show that the target damage probability increases with the increase of penetrating intersection area between warhead fragment and target. Combine with testing experiment and c ompare with the traditional method we can obtain warhead fragment s spatial position by light field imaging method, give calculation results of target damage probability, verifies correlation calculation method of warhead fragments and target damage feasible.
