摘　　要：为满足弹道导弹作战对战场时空快速精确协同的需求,采用先判断弹下点轨迹的交点,后解算空间交叉点的方法,建立了弹道空间交点的快速计算模型,其中,弹下点轨迹交点的判断采用球面解析几何的方法,弹道空间交点的解算采用步长加速法。模型有效地解决了满足战场时空规划需求的弹道空间交点快速计算问题。算例表明上述方法在计算准确度和计算效率方面均能满足要求,具有重要的工程应用价值。In order to meet the ballistic missile on the battlefield space fast and accurate collaborative de- mand, a fast calculation method of trajectory of space intersection is established. The method of elastic point track intersection judgment using spherical analytic geometry, the trajectory of space intersection calculation using the step acceleration method. Meet the demands of the battlefield in time and space planning model can effectively solve the ballistic space intersection calculation problem quickly. The cal- culation examples show that the above method in calculation accuracy and the calculation efficiency can meet the requirements, has important application value in engineering.
