基于目标逃逸机动预估的空空导弹可发射区

为适应无人自主空战条件下对空空导弹火控解算的特殊需求，提出了基于目标机动预估的空空导弹可发射区问题。首先，基于导弹-目标追逃对抗策略，设计了目标机动预估模型，根据导弹与目标的相对方位信息，实现对目标逃逸机动方式的预估；然后，基于多种实际约束，构建了导弹运动动力学模型；最后，设计了基于黄金分割搜索算法的可发射区边界求解策略，实现对可发射区边界值的快速精确搜索。仿真结果表明，空空导弹对初始位置位于所提出的基于目标机动预估的可发射区内的目标，具有更大的命中概率；该可发射区更加适应近距空战中目标逃逸机动的剧烈态势变化，有利于导弹战术使用性能的充分发挥。 

Air-to-air missile launchable area based on target escape maneuver estimation

In order to satisfy the special requirement for fire control of air-to-air missiles under unmanned air combat conditions, the problem of launchable area of air-to-air missile based on target maneuver estimation is presented. Based on the missile-target tracking escape countermeasure strategy, the target maneuver estimation model is designed. According to the relative position information of the missile and the target, the estimation of the target escape maneuver mode is realized. Based on a variety of practical constraints, a missile dynamics model is constructed. A launchable area boundary solving strategy based on the golden section search strategy is designed to achieve a fast and accurate search for the boundary value of the launchable area. The simulation results show that the air-to-air missile has a greater probability of hitting the target in the launchable area based on the target maneuver estimation proposed in the paper. The presented launchable area is more suitable for the dramatic change of the target escape maneuver in the close air combat, which is beneficial to the full play of the missile tactical performance.
