反舰导弹基于虚拟目标的大空域变轨弹道设计

Design of Large-space Variable Trajectory for Anti-ship Missiles Based on Virtual Target

基于虚拟目标的概念,设计了一种适合于三维空间情况的简单的比例 导引律。利用该导引律引导反舰导弹去追踪空间的虚拟目标,可以使反舰导弹 实现大空域变轨弹道。采用大空域变轨弹道有利于发挥反舰导弹的机动能力, 增加飞行弹道的多变性,从而提高反舰导弹的突防能力。最后,通过弹道仿真证 明了所提出的比例导引律是很有效的。

A simple proportional guidance law is designed for 3-demensional space, based on the concept of virtual target. An anti-ship missile is guided to track the virtual target in space by this guidance law so as to realize the large-space trajectory maneuver. Adopting the large-space variable trajectory, a missile can increase its maneuverability and the variability of its flight trajectory, thus it improves the penetration ability. Finally, the trajectory simulation illustrates that the proposed proportional guidance law is very effective.
