【摘要】 首先分析了着靶姿态对钻地弹侵彻的影响,并就某制导侵彻航弹要求弹着角大和射程远的特点,提出了解决方案,设计钻地航弹复合制导方案,即通过方案弹道加末端角约束比例导引律实现对钻地航弹射程和末段着靶姿态的要求。针对方案弹道设计PID控制律,提出了中末段制导方案转换条件,仿真结果表明弹药着地时具有高速且满足末端角度约束。更多还原

【Abstract】 How the earth penetrating weapon’s penetrating ability is affected by the terminal angle is analyzed.The long range and terminal angle constraint is the request of the guided penetrated bomb.The multiple guided projects,including the scheduled trajectory and proportional navigation with terminal angular constraint is designed to satisfy the range and terminal angle constraint demand of the guided penetrated bomb.The PID control law is designed.The transform condition of middle and terminal flight stage is presented.The numerical simulation result shows a high terminal speed,the terminal angle is satisfied also.更多还原
