Three-Dimensional Guidance Law for Missile of Varying Velocity against Maneuvering Target of Varying Velocity

应用李雅普诺夫稳定理论 ,提出一种三维制导算法。在算法设计中 ,既考虑了目标机动 ,包括目标速度的变化 ,又考虑了导弹速度的变化。为实现所提出的算法 ,进一步将与目标运动的加速度和速度方位信息有关的项归为两项 ,给出了其估计方法。仿真结果验证了该方法的有效性。

Based on Lyapunov stability theory, a three dimensional missile guidance law is presented. In the proposed algorithm, not only the maneuvering of a target, but also the variation of both missile's and target's velocity, are considered. To implement the proposed algorithm, the terms related to the information on the acceleration (including the variation of target's velocity) and velocity relative heading angle of the target are divided into two terms, and their estimations are given. Simulation results have shown the effectiveness of the proposed algorithm.
