自主战术决策是UCAV付诸作战使用的关键技术之一。建立了基于航迹坐标系下的UCAV运动方程，对三自由度的控制指令进行了改进，并以此对NASA提出的基本操纵动作库进行了定量描述。在此基础上，面向实际战场态势，依据模糊空战推理规则，设计了基于自主战术决策模块的自主战术决策方法。仿真结果表明，所研究的方法可以使UCAV在空战中进行自主决策，获得更大的战场优势，具有一定的参考和应用价值。

Autonomous tactical decision-making is one of the key technologies for Uninhabited Combat Aerial Vehicles(UCAV) in combat.In our study,the kinematic equations of UCAVs were built up in flight-path coordinate system,and the 3DOF control command was improved.Based on which,the basic manipulation database proposed by NASA was described quantitatively.Then,an autonomous tactical decision-making system was designed according to the actual battlefield situation and the air combat fuzzy inference rules.The simulation result shows that: with the proposed method,the UCAV can make decision autonomously in combat and obtain more superiorities in battlefield.
