摘要: 根据远程弹道导弹在发射过程中对外部空间扰动引力场信息的需求,运用梯度法对外部空间扰动引力进行研究,为克服远程弹道导弹扰动引力计算模型复杂、计算量大、不容易在弹上计算机上实时计算的缺点,利用3台计算机组成主从模式并行计算模型,快速解算外部空间扰动引力。实验结果表明,该并行方法可以满足弹载计算机快速计算的要求,并能达到较高的精度。

Abstract: In order to solve the demand of the information about the effect of the disturbing gravitation on the long-range missile emission in the outside space of earth, this paper adopts gradient method to solve the disturbing gravity in the outside space. To solve the problem that it costs a lot of time and can not be calculated in time when it computes the disturbing gravity about long-range missile as well as its complex model. It adopts the parallel method of principal and subordinate mode. Experimental result shows that adopting parallel method to solve the disturbing gravity of trajectory missile can reach the demand of fast computing by computer and get a high precision.

Key words: disturbing gravity of outside space, gradient method, principal and subordinate mode, parallel computing, trajectory missile, fast computing, load balancing
