弹道导弹弹头分导技术的研究是我国导弹技术发展的必然。文中依据弹道导弹多头分导原理,阐述了分导式多弹头导弹的分导工作过程。为了满足现代武器系统快速反应能力的需求,针对分导式多弹头导弹的弹道模型特点,提出了运用并行计算技术来快速提升弹道计算速度的方法,并建立了分导式多弹头导弹弹道并行计算模型。在Linux环境下进行仿真,结果表明,本方法能大幅度提高弹道计算速度,可以得到很高的加速比。

The technology of multiple independently targeted reentry vehicles(MITRV) of the ballistic missile is an important part of missile technology. The working proceed of MITRV was given according to its principle. To satisfy the request of fast reaction in modern weapon system, aiming at the model characteristic of MITRV trajectory, the parallel computing technology was advanced to improve the computing speed and the parallel computing model of MITRV was built. From the result in Linux environment, this method can significantly improve the trajectory computing speed and achieve a high accelerate rate.
