将导弹在一个攻击平面上的平行接近法的导弹与目标的相对运动方程组推广为三维空间中的导弹与目标的相对运动方程组，利用三维空间中的导弹与目标的相对运动方程组推导出了惯性坐标系下的弹道倾角和偏角的计算公式，给出了多段组合法生成航迹的离散算法。在此基础上，结合大气运动方程组(MM5方程)，建立了非标准气象条件下的平行接近法导引弹道模型。通过仿真对比分析了标准和非标准气象条件下的平行接近法导引弹道，验证了纵风主要影响导弹的射程，而横风主要影响导弹的飞行方向。最后使用 STK (卫星工具包)对2种气象条件下的某空空导弹攻击空中目标的导引弹道进行了视景仿真，逼真地显示了导弹飞行且命中目标的运动轨迹。

The relative dynamical equations of the missile and target on an attack plane of the parallel ap-proaching method are extended to the three-dimensional space in this paper.The calculation formulas of the traj ectory obliquity and drift angle are deduced through the relative dynamical equations of the missile and target,and multi-section traj ectory generation method is presented.Then,by integrating with the e-quations of atmospheric motion (MM5 equations),the guidance traj ectory model of the parallel approac-hing method is established under the non-standard weather conditions.Through comparison the guidance traj ectory of parallel approaching method under the standard and non-standard weather conditions is ana-lyzed,the result shows that the headwind mainly influences the missile's range and the crosswind influ-ences the missile's direction mainly.Finally,the visual simulation of an air-to-air missile's guidance traj ec-tory under two different weather conditions by the STK (Satellite Tool Kit)is realized,which exhibits the motion traj ectory of the missile approaching and hitting the target vividly.
