摘　　要：导弹发射时的环境温度会影响固体发动机的推力 ,推力的变化一方面影响导弹的精度 ,另一方面影响导弹的最大射程。根据推力与推进剂初温的关系 ,建立了计算标准弹道关机点参数偏差的数学模型 ,计算了这种误差通过制导方程高阶项引起的落点误差 ,并且对最大射程误差也进行了计算 ,同时 ,采用修正制导方程系数的方法 ,对落点误差进行了修正。仿真结果表明 。The temperature can effect the solid rocket thrust when the missile is launched. The thrust change effects missile's accuracy on the one hand, effects maxmum range on the other hand. This paper sets up a model that calculates the standard ballistic shut-down point parameters according to the relationship between the thrust and propulsion, calculates the impact error resulting from high order term of guidance equation, assess the maxmum range again. At one time, by method of modifying guidance equation coefficients, the impact error is corrected. The simulated results show that the impact error can be corrected by the method presented in this paper.
