摘　　要：提出了一种基于有向图(DG)模型的综合通信感知一体化(ISAC)系统分析方法。通过构建考虑环境约束和ISAC节点间协作/干扰特性的收发(T-R)模型,将基站主动天线单元(AAU)间的T-R关系抽象为与节点资源相关的有向边,从而有效表征基站间的协作与干扰特征。在此基础上,提出了资源分配(RA)优化方法,旨在满足感知能力和干扰水平等性能约束的同时,最小化ISAC立体覆盖系统成本。仿真实验和实际部署案例验证了所提方法在立体覆盖分析和资源优化方面的有效性,为大规模网络化ISAC系统的实现提供了理论依据和实践指导。A novel analytical method for integrated sensing and communication(ISAC)systems based on a directed graph(DG)model is presented.By constructing a Transmit-Receive(T-R)model that accounts for environmental constraints and the cooperative/interference characteristics among ISAC nodes,the T-R relationships between active antenna units(AAUs)of base stations are abstracted as directed edges related to node resources,effectively characterizing the cooperation and interference features between base stations.A resource allocation(RA)optimization method is then proposed,aiming to minimize the cost of ISAC three-dimensional coverage systems while satisfying performance constraints such as sensing capability and interference levels.Simulation experiments and practical deployment cases validate the effectiveness of the proposed method in three-dimensional coverage analysis and resource optimization,providing theoretical foundations and practical guidance for the realization of large-scale networked ISAC systems.
