| 摘 要： | 在战场态势估计中,常常需要判断事件发生的时间顺序,而对事件发生时间的观测往往含有不确定性。考虑时间测量的分布不确定性,讨论利用Bootstrap方法来模拟时间测量误差的分布特性,给出在Bootstrap模拟经验分布下的两个事件发生顺序的态势判别方法,建立相应的时间顺序关系的概率计算公式。

| Abstract: | In battlefield situation assessment,it always needs to judge the time sequence of events,however the measurement of time that an event happens contains uncertainty usually.The distribution uncertainty is considered,and the bootstrap method is used to simulate the distribution characteristics of time measurement error.The judging methods of time sequence of two events are discussed under bootstrap simulating empirical distribution.The probability calculating formulas of corresponding time sequence relationship are given. |
