摘　　要：文章就如何建立垂直发射武器的火力散布体模型及如何判断火力交叉的发生进行了研究。采用四元数方法建立了垂直发射武器的弹道仿真模型,通过仿真定性分析了不同误差因素对于弹道散布的影响;分析了初始扰动对弹道散布的影响,得到了散布半径随时间变化的函数;建立了以理想弹道为轴线的垂直发射武器火力散布体模型,模型中考虑了时间上的控制因素,减小了导弹武器空间散布体的范围,并提出了模型的解算方法。所建立的模型能够较为准确地描述不同武器火力散布的情况,并能对火力交叉做出判断。It was studied how to establish firepower dispersion model and estimate fire intersection for the vertical launch weapons. The ballistic simulation model of vertical launch missile was established by using quaternion method, and the effect on the ballistic distribution caused by different reasons was analyzed through the model. The influence of initial disturbance was discussed and the function, which describes the change of the radius of the distribution along with the time, was given. The model of the distribution of the missiles with the ideal ballistic as the axes and concerned time as one of the control element was built, and the method to solve it was presented. The model can describe the distribution of weapons exactly and estimate the appearance of the firepower intersection.
