摘要：
本文介绍了在商业港口环境中的集装箱峡谷内，于28 GHz频段进行的一次全面测量活动的结果。测量在集装箱峡谷内的多个点进行，考虑了两种集装箱堆叠方式和两个不同的发射机（TX）位置，使用配备旋转喇叭天线的窄带信道探测仪。测量用于评估方位角谱和空间相关性，以及峡谷内车辆对这些参数的影响。此外，测量数据用于验证一个仿真设置，从中获得峡谷内的路径损耗和仰角谱。最后，提出了峡谷内的传播模型假设，并证明其与测量结果一致。分析显示，与自由空间相比，路径损耗较低，同时角度扩展较高且空间相关性较短。
英文摘要：
This paper presents results from a comprehensive measurement campaign conducted at 28 GHz inside a container canyon within a commercial port environment. The measurements are performed at various points inside the container canyon, considering two types of container stacking and two different Transmitter (TX) locations, using a narrowband channel sounder equipped with a rotating horn antenna. The measurements are used to evaluate the azimuthal spectrum and spatial correlation, as well as the impact of a vehicle inside a canyon on these parameters. Further, the measurement data is utilized to validate a simulation setup from which the path loss and the elevation spectrum inside the canyon is obtained. Lastly, a propagation model inside the canyon is hypothesized and shown to be consistent with the measurements. The analysis show a low path loss compared to free space, as well as a high angular spread and short spatial correlation.
