具有末端攻击角度约束的新型末制导研究

New Terminal Guidance Method with Terminal Impact Angle Constraint

为了实现打击效果最优化,制导方法不仅要能获得最小的脱靶量而且要能够按照一定的期望攻击角度对目标实施打击。针对末端攻击角度约束这种特殊作战要求,详细推导弹目相对运动方程,得到了攻击角度与弹目相对运动状态相关的运动模型。基于Lyapunov方法设计了一类能够实现在全局范围内对期望攻击角度跟踪的制导方法,推导出了相应的制导律。通过数学仿真验证了该制导方法的正确性与可行性。

In order to achieve optimized effectiveness of combat, the guidance method is required not on- ly to be able to obtain the smallest miss distance, but also to hit target in accordance with attack-angle under the certain expectation. Aiming at meeting the particular requirement limited by terminal-attack-an- gle, the relative motion equation of missile-target is deduced, and the motion model is obtained by the rel- ative state of motion between attack-angle and missile-target. A guidance method that tracked the desired attack-angle in the global scope is designed based on Lyapunov method, and the guidance law is presen- ted. The correctness and feasibility of the guidance method is verified by mathematical simulation.
