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。 In this paper, we study a new target guidance law. This method adjusts the trajectory of the missile approaching the target from a changing perspective, which not only allows greater error of the target position estimation, but also can more effectively deal with the target maneuver and improve Missile hit rate. This paper also discusses the lower velocity limit of missiles that approach this target. Finally, the simulation of missile tracking process is given.
