基于方差分析的Monte-Carlo制导精度分配方法研究

Research on the Guidance Precision Distribution Method Based on the Variance Analysis

传统的Monte-Carlo制导精度分配法是将所有的误差源纳入到精度分配中,在处理多误差源、多误差水平分配时,会导致仿真时间的增加。为此,将方差分析引入待分配项的确定中,并以某空地导弹精度分配为例进行了仿真分析。仿真结果表明,基于方差分析的Monte-Carlo制导精度分配方法大大减少了计算时间,且所设计的精度分配方案能满足工程设计要求。

The traditional guidance precision distribution method based on the Monte-carlo puts all error sources into the precision allocation and therefore it will result in an increased simulation time when dealing with multi-error sources and multi-level allocation. In this paper, the variance analysis is introduced to determine the precision distribution and used to the precision distribution of an air-to-ground missile. Simulation results show that guidance precision distribution method based on the Monte-carlo with variance analysis greatly reduces the calculation time and the accuracy of the distribution plan can meet the design requirements.
