摘　　要：高超声速导弹可以利用导引头探测的信息实现高精度打击,针对导弹攻击目标时受到导引头探测视线的约束问题,提出了一种考虑视线约束的制导方法。在建立了高超声速导弹弹道与制导模型的基础上,分析了在视线约束情况下如果仍按照传统的制导方法将无法准确命中目标的问题。面对该问题,采用滑动虚拟目标和导弹锥形机动相结合的方式,推导了考虑视线约束下的制导律;并通过选取不同的偏差状态以及视线约束角度进行仿真验证。仿真结果表明,该方法对不同的视线约束角度以及偏差状态具有较强的适应性,能有效提高导弹的命中精度。The information detected by the seeker can be used for hypersonic missiles to achieve highprecision strikes.For the line of sight constraint by the seeker's detection as missile attacking targets,a guidance method considering line of sight constraints is proposed.A calculational model for the trajectory and guidance of hypersonic missiles is established.The problem that the target cannot be accurately hit using the traditional guidance method is also analyzed.Aiming at these problems,the guidance law under the line of sight constraint is derived by combining sliding virtual target and missile cone maneuvering.Different deviation states and line of sight constraint angles are selected for simulation.Simulation results show that the method has a strong adaptability to different line-of-sight constraint angles and deviation states.It can effectively improve the hit accuracy of the missile.
