图像制导导弹落角约束的制导律设计

A Design of Guidance Law of Inage Guiding Missile with Terminal Angle Constraint

针对某些图像制导导弹限制终端攻击角的作战要求,提出一种落角约束最优导引律。该导引律形式简单,易于工程实现。仿真结果证明,能满足脱靶量小的要求,对于某些机动的目标,该制导律都能够以期望的终端攻击角度命中目标,对于目标的机动具有较好的鲁棒性。

According to the requirements of image guiding missile with terminal attack angle constrain,a new terminal guidance law was deduced based on the optimal control theory.The guidance law is simple and convenient to be realized in engineering.The simulation result shows that the guidance law can be used to hit the varying accelerated targets with expected terminal attack angle.The law shows better robustness for maneuvering target.
