Cooperative Sensing Performance Analysis for ISAC in Heterogeneous Air-Ground Networks
摘要
Abstract
The emergence of the low-altitude economy imposes higher demands for highly integrated and reliable wireless systems capable of simultaneously supporting communication and sensing functionalities.Although integrated sensing and communication(ISAC)technology has been extensively studied,existing research primarily focuses on link-level or single-cell architectures within terrestrial environments.The potential of network-level,air-ground coordinated ISAC remains largely unexplored.To bridge this technological gap,a heterogeneous air-ground ISAC network architecture based on the coordinated multi-point technique is proposed.This architecture significantly enhances spatial diversity and sensing capabilities by introducing a cooperative hybrid mono-/bi-static sensing scheme.The proposed framework employs a two-tier base station deployment:master base stations are arranged in a hexagonal lattice,while slave base stations are distributed according to a Poisson point process.This structure concurrently supports communications for ground users and sensing for aerial targets.Furthermore,a comprehensive analytical framework is constructed for evaluating the integrated sensing and communication performance,which meticulously accounts for critical channel parameters and network configurations.Simulation results elucidate the inherent dependencies between cooperative sensing performance and key system parameters,particularly under multi-base-station cooperation and varying network density.These findings provide practical guidelines for deploying scalable and efficient ISAC networks in low-altitude economy scenarios.关键词
