针对海基远程弹道导弹精度分析小子样、多误差源等特点,从精度分析样本生成思路、误差源分类及弹道建模、误差生成等方面进行了研究。用数理统计分析方法建立了初始误差生成模型,用平台漂移原理建立了工具误差生成模型,用线性假设的方法建立了其它误差生成模型,提出了基于试验数据、误差生成模型和弹道仿真相结合的精度分析样本生成方法。算例表明,该方法易于工程实施,可用于不同射程的精度分析。
Aiming at the characteristics of small sub sample and multiple error sources of precision analysis of long-range sea-based ballistic missiles, this paper studied the generation of precision analysis samples, the classification of error sources, ballistic modeling and error generation. The initial error model was established by using the method of mathematical statistics and analysis. The tool error model was established by platform drift principle. Other error model was established by linear hypothesis. Based on the experimental data, the error model and the ballistic simulation Accuracy analysis sample generation method. The example shows that this method is easy to implement and can be used for the accuracy analysis of different range.
