传统的导弹制导法则是针对战斗机设计的，其速度（600-800 m/s）比弹道导弹低得多。为了了解拦截大气层内的战区弹道导弹在导弹制导方面是否困难，使用 MATLAB/Simulink 对两种不同的再入飞行器的轨迹及其拦截的最后阶段进行了仿真，同时拦截器由其自身的传感器引导。如果导弹制导系统的固有延迟很小（低于0.5秒），拦截总是成功的。再入飞行器遵循摆动轨迹，但摆动幅度很小，不会对拦截器造成问题。如果拦截弹在最后阶段开始时接近反向弹道，则导弹的高速度（2,600 m/s）也不会产生影响。因此，当前的导弹制导技术似乎足以对抗空气动力学稳定的导弹，但早期探测和跟踪对于成功至关重要。
Traditional missile guidance laws are designed against fighter aircraft, with a much lower velocity (600–800 m/s) than ballistic missiles. To see whether intercepting a theatre ballistic missile inside the atmosphere is difficult in terms of missile guidance, trajectories of two different re-entry vehicles and the terminal phase of their interception, while the interceptor is guided by its own sensors, are simulated using MATLAB/Simulink. The interception is always successful if the inherent delay of the missile guidance system is small (below 0.5 seconds). The re-entry vehicles follow weaving trajectories, but the amplitude of the weave is small and does not pose problems for the interceptor. Neither does the high velocity of the missile (2,600 m/s), provided that the interceptor is near the inverse trajectory at the start of the terminal phase. Consequently, current missile guidance technology seems to be sufficient against aerodynamically stable missiles, but early detection and tracking are essential for success.
