针对具有射击域的武器系统,研究其火炮身管对射击域的随机穿越特性。在给出随机穿越特性严谨数学定义的基础之上,借用概率转移阵,给出了待机时间、滞留时间及随机穿越周期均服从几何分布的结论,并演绎了它们的均值与方差,从而建立了这些时间指标与武器控制系统的结构和参数之间的联系。最后,以武器系统靶场试验数据验证了结论的可信度。
Taking aim at a class of weapon system with shooting domain, the stochastic passage characteristics for gun tube were studied. On the basis of the exact definition of stochastic passage characteristics, the conclusion, in which opportunity-awaiting time, residence time and stochastic passage period obey geometric distribution, was given by the transition probability matrix; their means and variances were also derived; the relations between the time indexes and the structure and parameters of weapon control system were established. Finally, the creditability of the results was proved by the test data of weapon system in proving ground.
