战略空中目标经典航迹匹配模型研究

针对战略空中目标经典航迹匹配问题，提出一种多属性加权关联匹配模型，重点解决了热点区域战略空中目标经典航迹提取及实时航迹的关联匹配。针对热点区域经典航迹库生成，应用凸包Graham’s Scan算法对航迹群进行聚类分析，提取经典航迹凸包并生成经典航迹库；针对实时航迹的关联匹配，提出一种多属性加权关联匹配模型，通过仿真试验确定位置、速度、航向等属性的最优权重。该模型已应用于某信息系统，有效提取了经典航迹活动规律并可以实时匹配经典航迹，同时，为空中战略态势研判提供了有力支撑。

Research on Classical Track Matching Model of Strategic Air Target

Aiming at the classical track matching problem of strategic air targets,a multi-attribute weighted association matching model is proposed,which focuses on classical track extraction and real-time association matching of strategic air targets in hot spot area.For the generation of classical track database in hot spot area,the convex hull Graham’s scan algorithm is used to cluster the track group,extract the convex hull of classical track and generate the classical track database.For the association matching of real-time track,a multi-attribute weighted association matching model is proposed,and the optimal weights of position,speed,heading and other attributes are determined through simulation experiments.The model has been applied to an information system,which effectively extract the classical track activity law and match the classical track in real time.At the same time,it provides a strong support for the research and judgment of air strategic situation.
