摘　　要：针对信号检测系统的性能还很难满足电磁频谱监测传感网要求的问题，设计一种基于多跳的混合型分布式信号检测系统，分析研究在衰落信道中基于多跳的混合型分布式信号检测系统的检测性能，推导检测概率和虚拟概率。理论分析与仿真结果显示，提出的混合型分布式信号检测系统能够获得比现有的并行分布式信号检测更好的性能。此外，多跳短距离通信使得簇头节点间的通信距离减小，从而使网络能耗减少。The performance of signal detection system isstill unable to meet the requirement of electromag- netic spectrum monitoring sensor network. To solve that problem, this paper proposes a mixed distributed detection system based on multi-hops and analyzes the detection performance of the proposed detection sys- tem in fading channel. The detection probability and false alarm probability are derived. Analysis and simu- lation results show that the proposed detection systemcan obtain higher performance than the parallel detection system, and canreduce energy consumption by cluster head nodes through shorterangemulti-hop communication.
