提出一种在威胁环境下对敌空战时，战机导引律设计方法。根据空战中存在的威胁因素，战机在空战过程中首先利用遗传算法进行远距导引设计，规避敌方防空威胁；然后根据滑模变结构理论设计近距空战导引律，并将两种作战机动导引进行融合。基于进化理论来构造规避路径，并利用卡尔曼滤波对机动目标进行状态估计，实现威胁回避和空中交战机动的组合导引。仿真结果表明，该组合导引律能够在复杂环境下有效地完成空战任务。

We put forward a design method of fighter guidance law for air combat against the enemy under threat environment.According to the threat factors existing in air combat process,the fighter first employs genetic algorithm to design the long distance guidance to avoid air defense threat from the enemy;then it designs the close distance air combat guidance law according to variable structure control (VSC),and fuses these two kinds of combat manoeuvre guidance.The avoiding path is constructed based on evolution theory,and the state estimation of the manoeuvring target is carried out with the help of Kalman filter,these realise the combined guidance of threat avoiding and air combat manoeuvring.Simulation results show that the combined guidance law can complete the task of air combat effectively under the complicated environment.
