摘要
在弹道导弹的被动段,根据受空气阻力的作用程度,其弹道可被分为自由段和再人段两部分。文献[1]对自由段弹道进行了仿真分析。文献[2]对再人段弹道进行了仿真分析。实际上,自由段和再人段之间有着密切的联系,可以通过这些联系.建立适用于、整个被动段的弹道方程组。最后。以某型近程弹道导弹为例对建立的模型进行了仿真,通过对仿真结果的分析,该模型能够较好的反映弹道导弹在整个被动段的运动特性。
In unpowered trajectory of ballistic missiles, according to the role of air drag from its trajectory can be divided into free- flight trajectory and reentry trajectory in two parts. The paragraph [-1] is simulation analysis for free-flight trajectory and the para- graph [2] is simulation analysis for reentry trajectory. In fact, the free-flight trajectory and reentry trajectory has close contacts, through these contacts,established unpowered trajectory of ballistic missiles applying to the entire trajectory equations. Finally, as an example of a certain model of short-range ballistic missiles to carry out the establishment of a simulation model, through simulation and analysis of results, the model can be a better reflection of the dynamic characteristics of ballistic missiles' unpowered trajectory.
