摘要
在分析经典导引律和现代导引律内在联系的基础上,利用有限可获的制导信息,提出了一种新的组合导引律,由比例项和前置角项组成,力图综合经典导引律和现代导引律的优点,结构简单,易于工程实现,并在基于目标大机动规避的假设下给出了机理解释;通过仿真验证,此方法具有末段弹道平直的优点。
Based on the detailed analysis of the classical guidance law and the modern guidance law, and using limited guidance information, a new integrated law was proposed which combined proportional navigation and fixed lead navigation. This guidance law tried to integrate the merits of the classical guidance law and the modern guidance law. It also had simple structure and was easy to actualize in the engineering. The mechanism was explained under the situation that the target escaped with high acceleration. The simulation results show the smooth terminal trajectory.
