摘要

─电磁波在隧道和矿井中的传播是一个科学研究领域，由于在墙壁和周围障碍物上有多次反射，因此很难建立模型。本文提出了一种基于超高频(UHF)波段的长距离传播模型、修正波导模型和远区传播模型加权和的新型地下隧道传播模型。根据发射器和接收器之间的距离将传播模型划分为五个区域。每个区域表现出不同的传播特性，并用基本传播模型的加权和建模。我们的模型在一个2米× 1.5米横截面和250米长的隧道中进行了测试。测量结果与提出的传播模型一致。索引术语─传播建模、地下隧道、地下通信。

Signal Propagation Modeling Based on Weighting Coefficients Method in Underground Tunnels

─ The propagation of electromagnetic waves guided in tunnels and mines is an area of scientific study which is hard to model due to multiple reflections on walls and surrounding obstacles. A novel propagation model for underground tunnels based on the weighting sum of the log-distance propagation model, the modified waveguide model and, the far zone propagation model for the ultra-high frequency (UHF) band is proposed in this paper. The propagation model is divided into five regions based on the distance between the transmitter and the receiver. Each region shows a different propagation characteristic and modeled with weighting sum of the base propagation models. Our model was tested in a tunnel with 2 m x 1.5 m cross-section and 250 m length. Measurement results are consistent with the proposed propagation model. Index Terms ─ Propagation modeling, underground tunnel, underground communications.

期刊介绍： The ACES Journal is devoted to the exchange of information in computational electromagnetics, to the advancement of the state of the art, and to the promotion of related technical activities. A primary objective of the information exchange is the elimination of the need to "re-invent the wheel" to solve a previously solved computational problem in electrical engineering, physics, or related fields of study. The ACES Journal welcomes original, previously unpublished papers, relating to applied computational electromagnetics. All papers are refereed. A unique feature of ACES Journal is the publication of unsuccessful efforts in applied computational electromagnetics. Publication of such material provides a means to discuss problem areas in electromagnetic modeling. Manuscripts representing an unsuccessful application or negative result in computational electromagnetics is considered for publication only if a reasonable expectation of success (and a reasonable effort) are reflected. The technical activities promoted by this publication include code validation, performance analysis, and input/output standardization; code or technique optimization and error minimization; innovations in solution technique or in data input/output; identification of new applications for electromagnetics modeling codes and techniques; integration of computational electromagnetics techniques with new computer architectures; and correlation of computational parameters with physical mechanisms.
