Design and Implement of Numerical Simulation System for Onrushing Missile versus Intercepting EKV

为更好进行机动突防及拦截仿真研究,设计了一个弹道导弹与大气层外动能拦截器(EKV)攻防对抗的数字仿真系统。在统一的空间与时间中,建立了弹道导弹的飞行状态模型、拦截导引模型、剩余飞行时间估计、脱靶量计算等系统算法模块,并对目标机动突防、比例与最优导引拦截等想定进行数字仿真。结果表明:该系统可在多种对抗环境下检测攻防性能,采用模块化设计便于算法升级或想定变换,为拦截、规避性能评估,攻防对抗策略研究等提供性能测试平台。

To research on missile maneuver and intercepting simulations better, a numerical simulation system for onrushing missile versus intercepting EKV was set up. With the same coordinate system and clock, the ballistic missile flight state model, EKV guidance model, the time-to-go estimation algorithm and miss distance calculation algorithm were all accomplished. At last, the scenarios that target maneuver, interceptor guided by proportional navigation （PN） and by optimal guidance law （OGL） were simulated in the simulation system. It indicates that the system can run well in such scenarios. It is designed by modularization that makes it easy to upgrade algorithm or scenario. The system provides a nice performance test flat roof to the missile maneuver, intercepting and drawing a counterplot.
