摘　　要：基于无动力滑翔弹气动力特性与动力学模型、中/末制导律与控制系统的飞行仿真模型,以及风场模型等,在一定的释放条件下,通过不同风场(即不同风向与风速的组合),计算了大量的可攻击区。利用VC++与Matlab飞行仿真软件,较为直观地比较了无风与不同风场中的无动力滑翔弹可攻击区及相应的六自由度(6DOF)飞行轨迹。大量的数据表明风场改变了无动力滑翔弹的可攻击区的形状及大小。因此,风场是影响无动力滑翔弹命中率与可攻击区的重要因素。当计算无动力滑翔弹的可攻击区时,随机风场必须考虑,这在实战中很有参考价值和工程实用价值。Based on flight simulation model of a no-power gliding missile （ including differential dynamic equations and missile guidance law in wind field）, attack zones （AZs） of the air-surface gliding missile were calculated considering a great deal of combinations of release conditions and different wind fields. AZ and their 6DOF flight trajectories of the no-power gliding missile in no-wind are compared with those in different wind fields. The numerous results show that those wind fields not only transfer the AZ shape into another one, but also change the AZ size. So wind field is a very important factor that affects no-power missile to reach the target, that means the stochastic wind field has to be considered when an AZ of no-power gliding missile is calculated, which possess reference values and practical engineering values in actual applications. In process of whole calculation and simulation, both VC ＋ ＋ and Matlab softwares were employed.
