过载约束下的大机动目标协同拦截

研究了非线性拦截几何下具有过载约束的多枚弱机动能力的导弹拦截强机动能力的目标的协同拦截问题。首先，在建立导弹的可达域、导弹的可行域以及目标的逃逸域这3个概念的基础上提出了非线性拦截几何下的基于逃逸域覆盖的协同拦截策略，并提出了基于标准弹道的设计方法。然后，给出了协同拦截制导律的形式，研究了导弹的末制导初始阵位、制导律参数以及导弹对目标机动的覆盖区域这三者间的关系，并设计了数值求解算法来实现对多弹的覆盖区域的分配、协同制导律的设计以及多弹初始拦截阵位的配置。最后，对理论结果进行仿真。结果显示，多枚机动性较小的导弹，通过初始拦截阵位的合理配置和协同拦截制导律的合理设计，可以实现对机动性能较强的目标的协同拦截。

Cooperative interception against highly maneuvering target with acceleration constraints

In this paper, the cooperative interception of multiple inferior missiles with acceleration constraints to intercept a highly maneuvering target is studied using the nonlinear interception geometry. Firstly, based on the establishment of the reachable region of the missile, the feasible region of the missile, and the escape region of the target, a cooperative interception strategy based on the coverage of escape region using nonlinear interception geometry and a design method based on the standard trajectory are proposed. Secondly, after giving the form of co-operative guidance law, the relationship between the initial position of the terminal guidance phase, the parameters of the guidance law, and the coverage area of the maneuvering range of the target is studied. A numerical algorithm is designed to realize the allocation of the coverage area, the design of the cooperative guidance law, and the configuration of the initial interception position. Finally, the theoretical results are simulated. The results show that multiple missiles with weak maneuverability can intercept highly maneuvering target through a reasonable configuration of the initial interception position and a reasonable design of parameters in the cooperative guidance law.
