Twin Studies on Electromagnetic Spectrum Situation

在车辆复杂电磁环境中,电磁频谱态势孪生可以为频谱态势补全提供孪生态势图用于验证算法的可靠性,以及为信号识别模块提供孪生频谱图训练数据。文章针对电磁信号真实传播环境复杂,信道的准确建模困难问题,提出采用射线跟踪方法 (RT方法),通过在重构的三维电子地图场景中建立确定性模型,对电磁频谱态势孪生进行研究。

In the complex electromagnetic environment of vehicles,electromagnetic spectrum situation twinning can provide a twinning situation map for spectrum situation completion to verify the reliability of algorithms,and provide twinning spectrum map training data for signal recognition modules.The article addresses the complex propagation environment of electromagnetic signals and the difficulty in accurately modeling channels.It proposes the use of ray tracing method(RT method)to establish a deterministic model in the reconstructed three-dimensional electronic map scene and study the twin of electromagnetic spectrum situation.
