Abstract：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.
