二次型一阶最优制导律的一种实现方案

基于二次型性能指标的一阶最优制导律对导弹指令响应的动力学滞后和目标的机动进行有效的补偿，有助于在远小于比例导引的过载需求下快速高精度拦截目标，值得深入研究。重点对基于雷达主动导引头的二次型一阶最优制导律实现过程中的信息测量与估计问题进行了研究，给出了视线转率测量和剩余飞行时间的计算方法参考。

Implementation of a Single-lag Optimal Control Guidance Law

The single-lag optimal control guidance law based on the linear-quadratic performance index compensates the optimal acceleration command for the lag of the missile dynamics and the manoeuvre of the target in advance. It helps a missile to intercept a target rapidly and precisely. This paper researches information measuring and estimating during the implementation of single-lag optimal control guidance law, which based on active radar seeker, and gives the ways of calculating the line of sight turning velocity and the residue fly time.
