为研究非标准条件下气象要素对导弹制导精度的影响，给出了一种适用于空地导弹在三维空间飞行的复合导引律，建立了非标准气象条件下的复合导引法导引弹道模型。同时给出了大气运动基本方程组(MM5方程组)易于编程计算的数值解法，采用变步长的四阶龙格库塔数值积分法，联立求解相关的微分方程组，对比分析了标准大气环境下比例导引法导引弹道和非标准气象条件下复合导引法导引弹道，得出了复合导引法导引弹道更接近真实的弹道。使用STK(卫星工具包)对某空地导弹的2种导引弹道进行了视景仿真，直观形象地显示了导弹飞行的运动轨迹。

In order to study the influence of meteorological elements on the guidance precision of missile un-der non-standard weather conditions,a type of combined guidance law applied to three-dimensional space is presented and a model of the combined guidance trajectory is established under non-standard weather con-ditions.An easy-to-program numerical solution of the basic equations of atmospheric motion is put forward and solved through numerical integral method of variable-step four orders Runge-Kutta combining the re-lated differential equations.By way of contrast with proportional guidance trajectory under the standard atmosphere,the result shows that the combined guidance trajectory is closer to actual missile's trajectory. Which directly and vividly exhibits the motion trajectory demonstrating the situation in flying and hitting the target.by STK.
