摘　　要：超视距多目标攻击逻辑决策和空战态势评估是超视距空战研究的主要方面,但对空战战术影响较大的战机飞行轨迹和飞行参数的研究较少。通过对超视距空战和视距内空战的比较,分析了超视距空战的空战过程。根据超视距空战迎头攻击战术的特点,建立了相应飞行轨迹的数学模型,并求解了载机速度、载机发射导弹速度、转弯速度、载机转弯半径、目标机速度、载机飞行时间、转弯时间和导弹飞行时间之间的关系。通过仿真分析了飞行参数对飞行轨迹的影响,并根据载机性能约束条件,求解了飞行参数的最优解。仿真结果表明,飞行轨迹模型和最优飞行参数设计的合理性和可信性,可为超视距空战战术、战法决策等作战应用提供重要参考。Multi - target attacking decision and air combat situation assessment for beyond visual range air combat are the main problems in researches for beyond visual range air combat. However, the researches on flight track and flight parameters which impact tactics a lot, are lacking. According to the comparison between beyond visual range air combat and within visual range air combat, we analyzed the process of beyond visual range air combat and its characteristics. A mathematic model for flight track of beyond visual range head - on air combat was established based on model for flight track to obtain the relation between velocity of interceptor, velocity of missile, velocity of swerve, radius of swerve, velocity of target, flying time of interceptor, swerving time of interceptor and flying time of missile. This paper analyzed the impact of flight parameters on flight track by simulation, and presented a method for optimal design of flight parameters. The simulation of air combat shows that the mathematic model of flight track and optimal design of flight parameters are valid and believable, which offers a reference for air combat tactics and opera- tional application.
