摘要
针对传统导弹的战斗部无法实现对目标在俯仰和方位上双定向的问题,为具有瞄准式战斗部的导弹建立了破片与目标相对运动模型。根据该模型及战斗部破片在不同瞄准角下飞散距离不同的特点,将战斗部中心破片最佳飞散距离作为瞄准攻击的依据,实现了瞄准式战斗部破片飞散方向的双向控制,推导出了引信起爆延迟时间的解析解。通过仿真证明了在现有的目标与导弹相对速度及脱靶量测量误差条件下,基于最佳飞散距离的瞄准方案可以应用于瞄准式战斗部的方向控制。
Considering that the traditional isotropic warhead of missile can not aim at the target in two directions of pitch and azimuth angle,we established a relative movement model of missile and target for the missile with gimbaled warhead. Based on the model and the fact that the fragments will spray for different distances at different aiming angles,we took the optimal spray distance the centre fragment as the basis for attacking,and realized the control to fragments in two directions. Then,the resolution of fuse booming delay time was calculated out. At last,the result of simulation proved that the with the current measuring error of relative velocity and miss distance,the aiming scheme based on the optimal flying distance can be applied in direction control of the warhead.
