Abstract

In order to evaluate the effectiveness of space target damage caused by projectile explosion in weapon range, it is difficult to give a scientific calculation model for target damage due to the uncertainty of projectile explosion position and target intersection state. In this paper, we study the probability calculation function of multiple projectiles hitting the target area by combining the principle of air defense and anti-missile mesh intersection and explosion. According to the fragment dispersion characteristics formed by the explosion of the projectile and the intersection penetration area of the fragment and the target, studying the calculation method of the target damage condition probability under the condition of shooting multiple projectiles in one test, and establishing the calculation model of the target damage probability of multiple projectiles' explosion fragments under the condition that the projectile effectively hits the target. Through the experimental test of the five element acoustic array projectile explosion point position testing system, we calculate the damage probability of multiple projectile explosion points to the target according to the probability function of the projectile hitting the target in the explosion and the damage function of the target scattered by fragments. The experimental results show that the theoretical simulation results are basically consistent with the target damage results calculated from the actual projectile explosion test data.
