摘要: 为增加巡航导弹低空突防的概率,在离线规划好航迹后,要保证导弹以最小偏差沿航迹飞行.通过仿真发现,传统的角指令法存在航路点切换时导弹过载超过指标要求,导弹越过障碍物时有较大的过顶时间的问题.为解决这一问题,提出了一种导弹纵向和横侧向的航路导引方法和指令生成方法,并以某型导弹低空突防为例,设计了飞行控制律.通过地形跟随六自由度仿真,比较了两种航路导引方法对地形跟随性能的影响.仿真结果都表明:采用这种纵向和横侧向航路导引方法和指令生成方法以后,该型导弹的地形跟随飞行性能得到了明显提高.

Abstract: To increase penetration rate for low attitude cruise missile, a minimum deviation of the missile along the flight path must be satisfied, after the flight path plan to be finished. During the missile flight simulation, missile overload exceeds requirement when waypoint is switching and overshoot time becomes extended. To solve this problem, new missile guidance method for longitudinal and lateral aisles and command generated method were proposed, control law of missile was designed to satisfy requirement of the missile low attitude penetration. By way of terrain following and terrain avoidance (TF/TA) 6-degree of freedom simulation, performances of two guidance methods on TF/TA were compared. Simulation results shows that, use this new guidance method of longitudinal and lateral aisles and command generated method, TF/TA performance of missile is increased.
