一种用于跟踪轨迹规划的新的导引规律

A New Guidance Law for Tracking Trajectory Planning

本文研究一种新的目标导引规律，这种方法通过变化的视角来调整导弹接近目标的轨迹，不仅能够允许目标位置估计有较大的误差，而且可以更有效地对付目标的机动运动，提高导弹的命中率。本文还讨论了用这种方法制导的导弹接近目标的速度下限。最后给出了导弹跟踪过程的仿真。

This paper studies a new object guidance law, which stems from the proportional guidance law through adjusting the visual angle in the missile's approaching process.This adjustment makes the resultant law be able to endure larger errors of object position estimations and deal with the object motion maneuver more efficiently.The minimum approaching speed of the missile is also discussed in this paper. Tracking processes of a missile guided by the proposed guidance law are also simulated to show its properties.
