基于射线追踪法的室内走廊环境电波传播研究

Research on Radio Propagation in Indoor corridor Based on Ray Tracing Algorithm

本文对受限环境中无线信道的电波传播进行预测研究。根据现状选择比较适合的射线光学方法,结合室内走廊环境重新建立射线追踪模型。由于在以往大多进行的是均匀横截面隧道环境下的研究,所以本文在进行均匀横截面隧道射线追踪模型构建后,将其延伸至非均匀横截面隧道中。对所提出的模型进行仿真研究,后结合接收天线与发射天线不同位置、高度以及走廊环境材料等因素进行实际实验,通过对比分析来验证所提出的室内走廊电波传播研究模型。

In this paper,we study the prediction of radio wave propagation in wireless channels in a restricted environment.According to the status,a more suitable ray tracing optics method is selected,and the ray tracing model is re-established in combination with the indoor corridor environment.Since most of the previous studies have been carried out in a uniform cross-section tunnel environment,this paper extends the uniform cross-section tunnel ray tracing model into a non-uniform cross-section tunnel.The proposed model is simulated and combined with the different positions and heights of the receiving antenna and the transmitting antenna,as well as the corridor environment materials.The experimental model is used to verify the proposed indoor corridor wave propagation model.
