获取EKV导引律信息是弹头实现中段智能机动突防的前提,为获取EKV导引律参数,提出一种快速辨识EKV导引律的方法。利用弹头红外成像系统得到EKV视线角的变化量,提出模板库辨识的方法对EKV导引律进行辨识;分析拦截器EKV和弹头的测量误差,并对EKV导引律进行辨识仿真。仿真结果表明模板库可以有效辨识EKV导引律参数,此方法可为工程应用和中段智能机动突防前期研究提供重要的理论参考。

It is the premise of achieving the intelligent mobile penetration of the ballistic missile to get the parameter of EKV guidance law. In order to get the parameter of EKV guidance law, the method of identifying the EKV guidance law in quick was proposed. The EKV guidance law was identified through the method of template library identifying based on the warhead infrared imaging system according to the observation of the change of the angle of the sight from warhead to EKV. The text simulated the identifying to the EKV guidance law considering the measurement errors of EKV and warhead. Simulations show that the template library was effective enough to identify the EKV guidance law and the method might be applied to the research of middle intelligent penetration and the engineering application.
