基于空中机动目标拦截的制导和引信及战斗部一体化设计研究

为实现对空间机动目标的可靠拦截，研究防空导弹制导盲区情况下常规破片战斗部的制导和引信及战斗部一体化设计方法。在已知目标最大机动能力作为先验信息条件下，通过目标最大机动能力估计制导盲区内目标潜在运动的状态集合;建立破片飞散的数学模型，根据目标状态集合和破片飞散特性求解防空导弹最佳交会状态和引信最佳起爆时间；采用Gauss伪普法，以末端弹目相对位置、弹目视线角和速度矢量夹角作为约束，求解导弹实时最优控制输入，使防空导弹到达最佳拦截位置。仿真分析结果表明，所提制导和引信及战斗部一体化设计方法能够实现引信最佳起爆控制和目标可靠拦截，对战斗部设计提供了依据。

Integrated Design of Guidance Law， Fuze and Warhead for Maneuvering Target Interception

An integrated design method of guidance law， fuze and warhead for conventional fragment warhead is studied to achieve the reliable interception of high maneuvering target in space in the presence of guidance blind zone of air defense missile. Under the condition that the maximum maneuverability of target is known as prior information, the potential motion state set of target in blind guidance zone is estimated from maximum maneuverability of target, a mathematical model of fragment dispersion is established, and the optimal intersection state of air defense missile and the optimal detonate time of fuze are solved according to the target state and the characteristics of fragment dispersion. The Gauss pseudo-spectral method is used to solve the real-time optimal control problem of missile with the constraints of the relative position of terminal missile and target, the line-of-sight angle of missile and the angle of velocity vector, so that the air defense missile can reach the optimal interception state. The simulation analysis shows that the integrated design method of guidance law, fuze and warhead can realize the optimal control of fuze and the reliable interception of target, and provide the basis for warhead design.
