在弹道导弹防御系统仿真中,需对战术弹道导弹的弹道进行仿真。一般而言,近程弹道导弹为抛物线型弹道,中远程弹道导弹为椭圆型弹道。依据上述两种弹道不同的特点,文中对这两种弹道分三段(助推段、自由飞段、再入段)建立了不同的仿真模型。该模型为反导体系的仿真提供了一个较为理想的作战对象,提高了仿真结果的可信度。

In the simulation of the ballistic missile defence system, the trajectory of tactical ballistic missile needs to be simulated. Generally, the trajectory of short range ballistic missile can be considered as parabola, while the trajectory of long range ballistic missile can be considered as ellipse. According to the deferent characteristics of those two types trajectories, deferent simulation models were built, each had three distinctive phases (boost phase, ballistic phase, reentry phase). This model can provide a better operational object in the distributed simulation system of missile conflict, and enhance the creditability of the simulation result.
