摘　　要：航天测控地面站网作为一个实际网络,它具有网络的相关属性;首先通过复杂网络方法构建了航天测控天地一体化二分网络,然后在二分网络基础上,提出了各专用测控系统的专用性参数α和通用性参数β来描述和区分不同的专用测控系统,利用Kendall相关系数和定义的相关性阈值K0构建了航天测控地面站相关性网络;以美国航天测控地面站网现状为例,对所提网络模型的有效性进行了仿真验证,应用相关性阈值(K0)和网络模块度(Q)曲线(K-Q曲线)分析了网络模型参数。研究结果表明,所提的相关性网络模型能较好的模拟测控地面站网络现状;网络模块度的峰值与|α-β|呈正相关,当|α-β|较大时,K-Q曲线整体呈现出正态分布特性。As an actual network,the aerospace TT&C ground station network has the relevant properties of the network.First, the binary network of integrating spacecraft and station is constructed by the complex network method.Then,based on the binary network,the specific parameterαand general parameterβof each special TT&C equipment are proposed to describe and distinguish different special TT&C equipment.The correlation networks of aerospace TT&C ground stationsare constructed by using Kendall correlation coefficient and defined correlation threshold K0 .Taking the status quo of the US aerospace TT&C ground station network as an example,the effectiveness of the proposed network model is verified by simulation.The parameters of the network model are analyzed by applying the correlation threshold(K0 )and the network modularity(Q)curve(K-Q curve).The research results show that the proposed correlation network model can better simulate the current situation of the TT&C ground station network. The peak value of network modularity is positively correlated with|α-β|.When|α-β|is large,the K-Q curve exhibits a normal distribution characteristic as a whole.
