摘要
建立了导弹的弹道数学模型。根据模型的条件、规定的导弹发射初始条件以及海情装订情况的目标初始值，对数学模型进行解算，得出理想弹道，并作为参考弹道。然后，加入干扰，进行弹道仿真相似计算及结果分析，得出对命中精度的影响。本文介绍了对干扰模型和系统模型进行校验的方法，得出校验结果。最后，通过仿真结果，分析了指示误差对导弹命中精度的影响。
A mathematic model of missile ballistic trajectory is set up. Based on the model condition and the initial condition given of missile launching as well as the initial value set of the target at sea state, a mathematic model is conducted and calculated, an ideal ballistic trajectory is derived and acted as a reference trajectory. Then an interference is aided, the comparability of trajectory simulation and its analysis are conducted, the influence factors of hit precision are given. This paper mainly introduces a check method of interference model and system model, and the results of check are gotten. At last, the effect of indicative errors to the hit precision of missile launching are analysed through simulation.
