摘　　要：在分析空间通信网络结构特征的基础上,设计了空间通信网络节点攻击模型,通过分析节点初始负载分配与节点容量、节点失效判定和负载重分配算法,建立了体系作战下空间通信网络级联失效过程模型,给出了基于作战环损失比的网络鲁棒性评价方法。最后通过实例对一种作战体系网络结构的级联失效过程进行仿真验证,仿真结果证明了模型的有效性,得到了攻击信息、节点容量和负载分配等参数对空间通信网络级联失效过程的影响关系,对体系作战下的空间通信网络结构优化和抗毁性研究有一定的参考意义。According to the structure characteristics of space communication network, a node attack model for space communication network was designed. A space communication network cascading failure model was proposed by analyzing the assigning of initial load and the capacity of node, the judging regulation of node cascading and the reassigning algorithm of node load. The evaluation method of network robustness based on the loss ratio of operation loop was put forward. The validity of the model is illustrated by a case of combat system network cascading failure process. The simulation results also revealed the relationship between the cascading failures results and the influence elements, such as the attack information, the capacity of node, the assigning of node load. The research has some referenced values on structure design optimization and survivability of space communication network.
