针对导弹要求限制终端攻击角度以发挥战斗部的最大效能,提出了一种适用于攻击地面固定目标的具有终端角度约束的最优制导律,并和已有的具有终端角度约束的最优制导律进行了比较.该制导律针对二阶弹体特性,采用最优控制方法,使导弹在命中目标的同时,满足终端角度约束.数字仿真结果表明,所提出的制导律能够实现终端角度约束条件,具有较高的制导精度.

A new optimal guidance law with terminal impact angle constraint is presented to satisfy performance requirements such as to enhance the effectiveness of missiles warhead to attack a non-maneuvering target.The comparison with an existed optimal guidance law is also made and proves the proposed guidance law is superior.The proposed guidance law considering the second order missile-body characteristics not only nullifies miss distance but also achieves a desired impact angle.Numerical simulation shows that the proposed guidance law can achieve the terminal angle constraint and have higher guidance precision.
