摘　　要：针对靶场导弹射程精确计算存在的问题,提出了利用微积分算法改进导弹射程的精确计算,具体采用曲线积分的方法,详细推导了一种不同于传统导弹射程精确计算的新方法,并提供了此方法的具体算法和模型。在理论分析的基础上,采用新方法对算例数据进行计算和分析,结果表明:用新方法计算得到的导弹射程精度达到亚毫米级,且精度与导弹射程大小无关。该方法已在靶场导弹射程的计算中得到成功应用。A calculus-based method is proposed to improve high accuracy calculation of the range of missiles. Unlike conventional methods, eurvilinear integration is used to derive high accuracy missile range. A detailed algorithm and model for the method are presented. Following theoretical analysis, experiment data is used in calculation and analy- sis with the new method. The results show that the missile range calculation accuracy of the new method reaches sub-millimeter level. Moreover, the accuracy has nothing to do with missile range. The method is already used in calculation of missile range at a test range.
