临近空间高超声速巡航导弹拦截问题研究

Researching Interception of Near-Space Hypersonic Cruise Missile

临近空间高超声速巡航导弹已逐渐进入武器化进程,对现有空间防御体系提出了严峻挑战。首先通过分析高超声速巡航导弹的典型飞行弹道,指出其巡航段是最为有效的拦截阶段,并提出空射拦截是一种主要拦截方式。其次,为了研究制导律和相关总体参数对拦截弹的拦截能力的影响,基于拦截问题搭建数学模型,并通过大规模系统的拦截弹与目标对抗飞行轨迹仿真,获取拦截弹在不同条件下的立体攻击区域。仿真计算结果表明,为实现对目标的有效拦截,拦截弹的立体攻击区应位于目标的近正迎头空域;在当前的仿真条件下,经典比例制导律无法完成对机动目标的拦截任务;论文得出的拦截范围和相关结论对于拦截弹总体设计具有一定的指导意义。

Near-space hypersonic cruise missile has gradually entered the weaponization process, which presents a challenge to existing space defense system. Firstly, we analyze a typical trajectory of hypersonic cruise missile; we point out that its cruise segment is the phase most vulnerable to being intercepted and propose that the air-launched interceptor is a major means for performing interception. Secondly, in order to study the influence of the guidance law and the overall relevant parameters on the intercept capability of interceptor, we build a mathematical model based on interception. And by a large-scale system flight path simulation of the interceptor flying against target, we obtain the three-dimensional attack area of interceptor under different conditions. The simulation results and their analysis show preliminarily that, in order to intercept the target effectively, the dimensional attack zone should be located near the target right head airspace. Under current simulation conditions, classic proportional guidance law can not complete the task of intercepting maneuvering target. The interception range and the relevant conclusions of this paper have a certain significance for interceptor missile.
