摘　　要：空战追击科目是空战BFM训练模拟器的重要项目,以航炮作为机载武器且UCAV处于逃逸态势的情况下,提出UCAV基于机动动作库逃逸机动决策的方法。首先分析了基本机动动作库,额外提出了五种机动动作并给出控制率;其次建立态势函数用以计算空战态势,采用滚动时域优化策略进行机动决策,并提出求解框架和改进的基于航炮示迹线的终止条件判据;最后进行了被敌方追击的典型态势下的空战仿真和验证,仿真结果表明提出的逃逸决策方法能让UCAV在不同战场态势情况下快速实现机动动作选择,有效地降低了被敌方击中概率,提高UCAV生存能力。The air combat pursuit subject is an important project of the air combat BFM training simulator.It analyzes the situation that the aircraft gun is used as the airborne weapon and the UCAV is in an escape situation,and the UCAV escape maneuver decision method based on the maneuver library is proposed.First,the basic maneuver library is analyzed,and five maneuvers are also proposed and the control rate is given;secondly,the situation function is established to calculate the air combat situation,and the rolling time domain optimization strategy is adopted to make the maneuver decision,and the solution framework and improved based The criterion for the termination condition of the artillery display trace;finally,the air combat in the typical situation of being pursued by the enemy was simulated and verified.The simulation results show that the proposed escape decision method can enable UCAV to quickly realize maneuver selection in different battlefield situations,effectively reduce the probability of being hit by the enemy and improve the survivability of UCAV.
