考虑到在三维空间从不同角度跃升俯冲攻击,对比例导引律进行改进,同时引入俯仰角和偏航角限制条件,提出带碰撞角偏置项的三维比例导引律(3DBPNG/AC).根据跃升俯冲攻击样式的特点,在导引律中加入控制规则函数,使弹目距离满足条件时开始跃升机动.相对于传统的跃升俯冲方案,本文所设计的方案只需要指定碰撞时俯仰角、偏航角及跃升时弹目距离.仿真表明,该方案能实现反舰导弹的全方向跃升俯冲攻击,飞行弹道平滑,跃升高度小,指令过载变化平缓.%To study the problem of climb-dive attack style with all aspects in the three-dimensional (3D) space, this paper propose a new 3 D biased proportional guidance law with angular constraint (3DBPNG/AC)to get all aspects in climb-dive attack style. Considering the constraint conditions of back-to-turn ( BTT) missile's overload and climb-dive attack style, the control expression was given which point out the climbing moment. Few parameters were using in the new guidance law comparing with the formal guidance law. The feasibility and the fine ballistics performance of the new guidance law were verified by the simulations of the characteristic trajectory. The verified result shows that the new guidance law is satisfied with precision guidance in all aspects climb-dive style,and have more predominance in climb attitude and control order.
