针对具有射击门体制的武器系统,研究其因加入射击门而产生的射击延时。藉助于概率转移阵的概念,定义了超速、欠速概率转移阵,导出了概率转移阵的估计式,给出了误差可小于期望值的射击延时分布函数,证明了该射击延时分布函数以及其可任意趋近的上界与下界均服从PH分布。最后,以试验数据验证了结论的可信性。
The shooting delay time as result of the equipped shooting gate is studied for the weapon system with shooting gate. On basis of the concept of transition probability, the faster transition probability matrix (FTPM) and slower transition probability matrix (STPM) are defined to estimate transition probability matrix which is used to compute the distribution of shooting delay time. This estimation is employed to deduce the shooting delay time distribution function whose error is less than the expected value. Then the shooting delay time is proved to be Phase-Type (PH) distribution, so are its upper and lower bound which arbitrarily trend to accord. At last, the practical test data validate the creditability of the results.
