山地场景下3D射线跟踪的应用分析

山地场景海拔落差较大,地势起伏且遮挡多,传播环境复杂.与传统SPM传播模型相比,3D射线跟踪模型更好的反映了电磁传播的反射、绕射和衍射等场景,且模型参数也更加丰富,因此,会更准确合理.本文主要通过在云南某山地场景进行CW测试,使用3D射线跟踪传播模型进行模型校正并分析模型校准的结果,深入分析了在山地场景采用3D射线跟踪...

Application analysis of 3D ray tracing in mountain scene

The mountain scene has a large altitude difference, and the terrain is undulating and obstructed. The electromagnetic propagation environment is complex. Compared with the traditional SPM propagation model, the 3D ray tracing model better reflects the reflection, diffraction and diffraction of electromagnetic propagation. And the model parameters of 3D ray tracing are more abundant. Therefore, it will be more accurate and reasonable. This article mainly conducts CW testing in a mountain scene in Yunnan . Use the 3D ray tracing propagation model for model calibration and analyze the results of model calibration. It can be seen that it is reasonable and feasible to use 3D ray tracing propagation model in mountain scenes.
