为了准确计算毁伤元延时起爆时间、提高超近程系统拦截空中目标的有效性,采用线性切割器作为毁伤元,且研究线性切割器的原理及特点,在地面坐标系中建立线性切割器和目标的运动模型。通过对模型的计算及分析得到毁伤元最佳起爆延时时间段,它对超近程反导的弹目交汇时间计算有一定的指导意义。同时得到在最佳起爆延时时间段对线性切割器的射角及时调整可以更有效的拦截目标。

In order to offer the best delay detonator time of damage unit accurately, and improve the efficiency of aerial target inter-ception in super short-range air defense weapon system the principle and characteristics of the linear shaped charge which was a-dopted as damage unit were investigated, and the movement model of linear shaped charge and the target was built. The best delay detonator time of the damage unit was obtained based on calculation and analysis; the result had guiding sense for calculating the time of short-range antimissile. We can also draw a conclusion that the linear shaped charge can intercept target more efficient by regulating the shooting angle in the best delay detonator time.
