一种基于图模型的空间态势理解方法

An Approach for Space Situation Comprehension Based on Graph Model

近年来机构和学者围绕空间态势感知任务,已形成了大量基于空间目标独立节点的目标跟踪、检测、识别、计算等相关理论和技术研究成果,面对低轨空间目标数量激增、高轨不断新增各类具有对抗背景的敏感目标的新形势,对空间态势认知能力提出了更高的要求。通过图模型对空间态势系统进行建模,设计构建双层空间态势理解结构来实现包含关系影响的单节点到系统层面的嵌入式映射,并通过进一步形成对态势整体的量化表示,通过实例验证所提方法的可行性,为基于空间态势感知信息、形成对整体空间环境和力量的态势理解及后续态势预测分析提供了思路和方法。

In recent years,the institutions and scholars have been focusing on the space situation awareness task and have formed a large number of such relative theories and technical research achievements as target tracking,detection,recognition,calculation of independent targets in space,however,as for the situation that meanwhile the number of low-orbit space targets proliferates,the sensitive targets with confrontation background constantly increase in the high orbit environment is constantly increasing.The higher requirements is proposed for providing the commander with auxiliary decision making with better and faster space situation cognition ability.A graph model is used to model the space situation system,and a two-layer space situation comprehension structure is designed and constructed to realize the embedded mapping from the single node to the system level containing the influence of the relationship.By further forming a quantitative representation of the overall situation,the feasibility of the proposed method is verified by an example.It provides ideas and methods to comprehend the overall space environment and forces based on space situation awareness information and to predict and analyze the subsequent situation.
