摘    要:为了对抗敌方远程舰空导弹的拦截,提高突防能力,反舰导弹的飞行弹道应采用大空域变轨弹道。基于虚拟目标的概念,建立了导弹-虚拟目标的空间追逃模型,设计了一种考虑末端落角约束的变结构制导律。先设置不同的空间虚拟目标,然后,利用所设计的制导律引导反舰导弹去追踪虚拟目标,反舰导弹实现了各种各样的大空域变轨弹道。只要虚拟目标的参数设置合适,在飞行中导弹的各项性能指标都能满足要求。弹道仿真表明,所设计的制导律是很有效的。

关 键 词:大空域变轨弹道  虚拟目标  变结构制导律  反舰导弹

Abstract:In order to withstand the interception of ship-to-air missile and increase the ability of penetration of anti-ship missile,the flight trajectory of anti-ship missile ought to adopt the large-space variable trajectory.The model of missile virtual target pursuit-evasion was constructed,basing on the concept of virtual target.A variable structure guidance law is designed considering the terminal angular constraint.The different virtual targets were placed in the space firstly,and then the anti-ship missile was guided to track the virtual targets by the designed guidance law,and all kinds of large-space variable trajectory were gotten for the anti-ship missiles.So long as the parameters of the virtual targets were met appropriately,all performance indexes of the missile was fitted for the requirements in flight.The trajectory simulation shows that the designed guidance law is very effective.
Keywords:large-space variable trajectory  virtual target  variable structure guidance law  anti-ship missile
