摘　　要：正确获取制导信息是进行精确制导的前提。虽然国内外对各种制导信息提取技术进行了很多研究,但还没有在这方面进行系统地总结。首先按照理解的直观性对制导信息进行了分类和归纳,探讨了常见制导律设计中用到的制导信息类型。分析了跟踪滤波和跟踪制导的区别,可知制导信息的数量与制导目的没有必然联系。在仅将目标当作点目标或面目标考察的基础上,提出了研究三维目标的六自由度信息获取问题。目标姿态信息是一种新型的重要制导信息,归纳了目标姿态信息对于精确制导研究的重大意义。对国内外制导信息提取技术的研究的现状进行了总结,建议积极开展目标姿态信息识别及其精确制导的相关研究。Accurate guidance information is the premise condition of precision guidance.In this paper,guidance information was classified and summarized firstly according to straight comprehension.Types of guidance information used in usual typical guidance law design were discussed.According to the tracking filtering and tracking guidance results,there was no relationship between guidance information quantity and guidance goal.On the basis of regarding three-dimensional target as point or plane one,the extraction of 6-DOF information（including position and pose） was put forward.The great significance of target pose information in precision guidance was concluded,and the research status of guidance information extraction was summarized.At last,developing research on pose estimation and the relevant guidance technique were suggested.
