摘要
利用复杂网络对卫星重要度评估展开研究。将卫星抽象成复杂网络中的节点,分析了该网络拓扑结构的动态特征;基于卫星的运动学模型及可视性判定模型,给出了网络拓扑结构的确定方法;分析了网络节点、节点连接边及相邻节点的计算指标,在此基础上建立了基于灰色关联度(GRD)的节点重要度评估模型。仿真结果表明,文中模型可以有效评估卫星的重要程度,为作战决策人员提供理论支撑和技术支持。
The paper researches the efficiency evaluation of satellite based on complex network. Satellites are represented as nodes in a complex networks. The authors study the dynamics and the identification method of the network topology architecture based on the dynamics and visibility model of satellite. The indexes of node,node connecting,and adjacent node are analyzed. Then,the evaluation model of node important degree is established based on Grey Correlation Degree（GRD）. The simulation result indicates that the model of the paper evaluates the efficiency of the satellite and provides the technology support for decision-maker.
