摘要

针对毫米波，特别是毫米波的高端三维通信，由于毫米波散射对粗糙地面和墙面的影响，使得仅采用镜面反射是不可能的。基于28 GHz不同入射角下墙体和地面的测试数据，得到了不同入射角下毫米波散射信号的分布，分析了墙体和地面的散射特性。结果表明，不仅在墙面和地面镜面反射方向附近存在漫射散射现象，而且在其他方向上也存在漫射散射现象。因此在光线追踪方法中引入漫射散射就显得尤为重要。

Experimental study on surface scattering characteristics of wall and ground in the millimeter wave

In view of the millimeter wave, especially the high-end three-dimensional communication of the millimeter wave, the influence of the millimeter wave scattering on the rough ground surface and the wall surface makes it impossible to adopt the specular reflection only. Based on the test data of the wall and ground surfaces at different incident angles at 28 GHz, the distribution of the scattering signals of the millimeter wave at different incident angles is obtained, then the scattering characteristics of the wall and the ground surfaces are analyzed. The results show that there is not only a diffuse scattering phenomenon near the direction of the specular reflection on both the wall and the ground surfaces, but also in other directions. So it is especially important to introduce diffuse scattering in the ray tracing method.
