Correlation on the object surface at mm-wave

This article focuses on the propagation characteristics due to the rough surface of the object. On the rough surface, the reflected wave becomes scattered from different positions on the surface. The degree of the scattering depends on the incident angle and on the roughness of the surface in comparison to the wave length. In this article, the roughness degree of the surface was estimated using the novel analysis method based on ray tracing. In results, the received power strength in the indoor environment and the cross-correlation in comparison to roughness degree were shown and described.
