针对目标机动对导弹效能的影响,首先介绍了典型的目标强机动类型并对其进行数学建模,并基于某型中远程空空导弹数学模型(气动模型、运动模型、导引率模型等),利用改进的二分法仿真计算了目标强机动下的导弹攻击区变化趋势;分析了不同发射条件下目标强机动对导弹命中概率的影响。仿真表明:目标强机动能够有效缩小导弹迎头攻击距离,并且能够规避在导弹最大可攻击区和不可逃逸区之间发射的导弹。

In order to study effect of target maneuver on missile effectiveness, strong maneuver type and mathematic model of target were presented firstly. The missile attacking area in environment of strong maneuver target was calculated by the improved dichotomy based on the mathematic model of an air-to-air missile, and the effect of strong maneuver on hit probability of missile under different launch conditions was analyzed. The simulation results indicate the strong maneuver of target can markedly reduce missile head-on attack distance, and the strong maneuver target can avoid missile attack being launched between maximum attack area and non-escaped zone.
