基于虚拟目标的KKV逆轨拦截导引方法

KKV Guidance Law for Exoatmospheric Head-on Interception Based on Virtual Target

为充分利用大气层外目标飞行特点,实现逆轨拦截,提出了基于虚拟目标的动能拦截器大气层外逆轨拦截导引方法;由预测命中点推导了虚拟目标的运动状态,以低速运动的虚拟目标代替真实目标,以追踪法为导引方法,实现逆轨拦截;通过仿真验证,这种方法能很好的实现逆轨拦截,且弹道平直,脱靶量小。

To make good use of the characteristic of the exoatmospheric flying and to realize Head-on inter- ception, the KKV guidance law, which is based on virtual target, has been propounded. The state of mo- tion of virtual target which is used to replace the real target has been inferred from the predicted hit point to reduce the relative speed and to realize head-on interception by the stern chase method. In the end, it is suggested by the result of final simulation that preceding method can achieve the Head-on interception in small miss distance and flatten trajectory.
