为评估中口径预制破片弹反导能力,针对某预制破片在舱室内的排布方式,分析开舱后破片运动规律,获取开舱距离和弹幕形状参数,建立中口径预制破片弹对某反辐射导弹的射击效率模型。采用仿真模拟法获得给定射击误差和近炸引信启动准则条件下的反导毁伤概率。计算结果表明:一定引战配合效率下中口径火炮近距离具备较好的反导能力;通过优化火控弹道解算开舱距离可提高中口径预制破片弹反导能力。

To evaluate antimissile capability of medium caliber gun, a single layer arrangement of prefragments in compartment is put forward. The split distance and barrage shape characteristic parameter are got by analyzing spacial distribution of prefragments after separation of the shell. Firing efficiency model of medium caliber pre-fragmented projectile against ARM is set up. Antimissile kill probabilities are calculated by simulation method while antimissile fire errors and fuze actuation criterion are determined. Simulation results show that medium caliber gun possesses better antimissile capabilities in short range under certain warhead-fuze matching effectiveness. Besides, optimizing the split distance of fire control ballistic solution can improve the antimissile capability of medium caliber pre-fragmented projectile.
