摘要
为了实现反舰导弹的大空域变轨,提出了一种三维虚拟目标比例导引律。该导引律利用简单的控制指令就能控制导弹完成复杂的大空域变轨。采用变轨弹道可以提高导弹的机动性,有效地对抗敌方反导武器系统的拦截,提高突防能力。同时,采用变轨弹道可以增大导弹的射程,实现防区外发射,从而有效地提高发射平台的生存能力。最后,通过仿真实例证明所提出的导引律是很有效的。
In order to realize large airspace transfer orbital trajectory of an anti-ship missile, a 3-dimensional virtual target′s proportional navigation guidance(PNG) law is proposed. This guidance law enables a missile to complete this complicated transfer orbital trajectory only using simple control instructions. Adopting the transfer orbital trajectory, a missile can increase its maneuverability, and effectively withstand the interception of enemy anti-missile weapon system, and improve the penetrability. Moreover, the missile can enlarge its range of attack and realize launching out of the field of enemy defense, thus, the survivability of launching platform is effectively improved. Finally, a simulation example is illustrated to prove that the proposed guidance law is very effective.
