Abstract

In this work, we have considered the problem of the urban propagation and we chose to use the deterministic method beam ray tracing (BRT). This is an evolution of the ray tracing method based on the propagation of the beams instead of the rays. In particular we analyze the contribution of multi diffracted rays. Subsequently we investigate the difference of the order of magnitude between a sequence o two simple diffraction and a double diffraction.
一种用于室外传播的双衍射光束追踪的新方法
在这项工作中,我们考虑了城市传播问题,我们选择了确定性方法光束追踪(BRT)。这是基于光束传播而不是射线传播的光线追踪方法的一种演变。我们特别分析了多重衍射射线的作用。随后,我们研究了两个单衍射序列和一个双衍射序列之间的数量级差异。
