摘　　要：提出了一种威胁环境下融合威胁回避战术的战机导引律设计方法。根据威胁环境的特点,分别设计目标引力场和防空威胁力场;且根据人工合力场确定最佳追踪方向;然后与组合导引律进行融合。基于高斯函数和模糊多属性决策理论来构造防空威胁力场,数据存储量小,实时性好,且能够处理模糊不确定性信息。仿真结果表明,该导引律能够同时实现威胁环境下的目标追踪和威胁回避机动;通过参数调节可实现攻防战术的协调运用,且实现容易。A new approach to guidance law design integrating the threat avoidance tactic for fighter under the environment with threat was proposed.Target attractive force field and air defense threat force field were designed according to the characteristic of the environment;the optimal pursuit heading was determined by the artificial resultant force field.Then it is used in the combined guidance law.The air defence threat force field was constructed based on Gauss function and fuzzy multiattribute decision,which needs little memory space,can be computed real-time and deal with fuzzy and uncertain information.The simulated results show that the new guidance law can realize threat avoidance while pursuing the target even under the environment with threat;by adjusting the parameters it can make a balance between attack and defense which is easy to realize.
