为了分析集束箭形弹反直升机作战的有效性,文中通过建立毁伤概率分析模型,计算了集束箭形弹对抗直升机的毁伤概率。结果表明,在一定的射程上,由一定数量的集束箭形弹组成的火力单元对直升机具有较高的毁伤概率,从而使得集束箭形弹成为了一种有效的反直升机武器;更进一步地,通过对比分析不同子箭飞行距离下的用弹量,提出了优化武器系统作战效费比的方法和途径。

With development of missile penetration technology, higher and higher demand is required eagerly to achieve the characteristics of attack missile early. Based on the characteristics of boost-phase of the ballistic missile, the regularity for change of attitude angle was got. With the change of attitude angle, the RCS time series of ballistic missile were calculated by the combination of physical optics (PO) and the method of equivalent current, and the result was compared with the detached missile. The result shows that the RCS time series of the boost-phase of ballistic missile embody the motion characteristics of missile, and time and velocity of detachment can be achieved preliminarily. It has important significance for antimissile defense.
