摘要
针对倾斜发射的轻型反坦克导弹,分析了下沉角速度对弹道高度的影响,对弹道初始下沉角速度和指令攻角之间的关系进行了研究。研究结果表明:下沉角速度与指令攻角呈线性关系,由此提出了通过下沉角速度插值指令攻角的自适应计算方法。通过这一方法解决了不同下沉角速度对弹道高度影响的问题,使导弹的末制导弹道具有较好的一致性,不但降低了控制系统复杂度,同时也提高了导弹的命中精度。
The influence of sinking angular velocity on ballistic height is analyzed in detail.The relationship between the initial sinking angle velocity of trajectory and the command angle of attack is studied.The results show that the sinking angle velocity is linear with the command angle of attack.Through this method,the impact of different sinking angular velocity on trajectory height is eliminated,thus making the terminal guidance trajectory of the missile highly consistent,which not only reduces the complexity of control system,but also improves the hit accuracy.
