面向通信感知一体化的室内太赫兹信道反射与透射特性研究
Research on indoor THz channel reflection and transmission characteristics for integrated sensing and communication
摘要
Abstract
The indoor terahertz(THz)wave reflection and transmission characteristics were clarified as essential for the construction of an integrated channel model for terahertz integrated sensing and communication(ISAC).Measurement campaigns were carried out on seven indoor materials at 130~134 GHz using a vector network analyzer-based measure-ment platform,and the frequency dependence and incidence angle dependence of the terahertz channel reflection and transmission characteristics were analyzed,which were compared with the measurement results at 282~290 GHz,to have the reflection loss characteristics in the two frequency bands revealed.A quantum particle swarm optimization algorithm was used to extract the material electromagnetic parameters,and a joint frequency-incidence angle model of the reflec-tion coefficient was proposed.The results are shown to indicate that the variation rule of the reflection coefficient with frequency and incidence angle can be accurately portrayed by the model.The material propagation coefficient database of the 130~134 GHz band is supplemented by the research results,the electromagnetic parameter dataset is enriched,and the reflection coefficient model is established.The data basis and model reference for the detection,identification,and environmental reconstruction of the terahertz ISAC system are provided.关键词
