摘　　要：针对导弹发射后可攻击区的计算问题,基于导弹与目标的运动模型,论证了风场对弹道以及命中结果的影响,在此基础上考虑目标机动和随机风场的影响,提出了一种精度较高、运算量较小的平移数值算法,对导弹的可攻击区进行了数值仿真计算并研究了其物理性质。仿真实验结果表明,通常情况下,发射一段时间后拦截导弹的可攻击区范围会受随机风场和敌我态势的改变而产生变化,相对于传统的导弹可发射区只能反应射前敌我态势,实时性较差的缺点,本文所提出的可攻击区算法对未来战场态势快速变化的空战环境具有更好的适应性。Aiming at the calculation of the missile's attack zone after launch,based on the motion model of the missile and the target,the influence of the wind field on the trajectory and hit results is demonstrated.On this basis,under consideration of the influence of the target's maneuver and random wind field,a translation numerical algorithm with high precision and less computation is proposed.The missile's attack zone is numerically simulated and its physical properties are studied.The simulation results show that,generally,the range of the interceptor missile's attack zone can be affected by the random wind field and the change of the enemy and friend situation after a period of time.Compared with the traditional missile's attack zone which can only reflect the enemy and friend situation before the launch,and has poor real-time performance,the attack zone algorithm proposed in this paper has better adaptability to the air combat environment with rapid changes in the future battlefield situation.
