| 摘 要： | 本文对研究导弹系统模拟打靶的蒙特卡洛法与统计协方差法进行分析、比较。蒙特卡洛法简明、直接,但试验次数要求1000次以上,方能有仿真的效果。统计协方差法可以用来近似分析非线性系统,研究由输入干扰引起的围绕标准弹道的小偏差,一般效果比蒙特卡洛法好。

| Abstract: | This paper presents the analysis and comparison between Monte carlo method and statistical covariance method which are used to research analog target of missile system. Monte Carlo method is simple and direct, but the times of experimental must be more than 1000 to obtain the effective simulation result. The statistical covariance method can be used to approximately analyse non-linear system and research the small deviation abut standard trajectory caused by input disturbances. Generally, the result is better than Monte carlo method. |
