摘要: 以突防概率作为评价标准,研究了突防导弹作正弦摆动突防机动时的突防效果.拦截-突防问题的模型为线化平面相对运动方程.用共轭系统分析法,得到了该模型在突防导弹摆动式突防策略的作用下,拦截导弹的脱靶量解析解,它由暂态分量和稳态分量组成.研究了突防持续时间按正态分布时导弹的突防概率以及这两部分对突防概率的贡献.Abstract: Effectiveness of weaving maneuver strategy of a missile when it passes through a Missile-Defence-System(MDS) is addressed. A linearized planar engagement model is used. Closed form solutions for the miss distance of interceptor are derived from the case where the interceptor's guidance system is modeled by a first-order lag and the maneuver acceleration is unlimited. The miss solutions consist of two components, one is the transient, the other is the steady. The effectiveness is measured in terms of the break-defence probability over a set of engagements in which the weaving-durations are normally distributed around its desired value. Comparisons are made between the effectiveness of the transient and the steady weaving maneuver strategy .
