本文利用8 GHz带宽的伪随机二进制序列时域信道测深仪对60 GHz频段的多径传播环境进行了分析。本研究的主要目标是分析一辆载有全向天线发射机的移动汽车与位于装有手动定向喇叭天线的建筑物内的固定接收器之间的多径分量（MPCs）传播。本文简要介绍了优势MPC震级的时间依赖性，展示了周围植被对RMS延迟扩展和信号衰减的影响，并统计评价了产生优势反射分量的道路的反射特性。为了了解mpc如何通过信道传播，我们使用带有受控接收器天线跟踪系统的自动测量系统测量并分析了汽车周围静态环境中的功率和RMS延迟传播分布。我们给出了一些例子，说明在天线跟踪过程中MPC的大小是如何变化的，并证明了一栋建筑物和停在测量车附近的几辆车会产生大量的MPC，该装置的动态范围约为50 dB。
The paper deals with an analysis of multipath propagation environment in the 60 GHz band using a pseudo-random binary sequence-based time-domain channel sounder with 8 GHz bandwidth. The main goal of this work is to analyze the multipath components (MPCs) propagation between a moving car carrying a transmitter with an omnidirectional antenna and a fixed receiver situated in a building equipped with a manually steered directional horn antenna. The paper briefly presents the time dependence of the dominant MPC magnitudes, shows the effect of the surrounding vegetation on the RMS delay spread and signal attenuation, and statistically evaluates the reflective properties of the road which creates the dominant reflected component. To understand how the MPCs propagate through the channel we measured and analyzed the power and the RMS delay spread distributions in the static environment surrounding the car using an automated measuring system with a controlled receiver antenna tracking system. We give some examples of how the MPC magnitudes change during the antenna tracking and demonstrate that a building and a few cars parked close to the measuring car create a lot of MPCs detectable by the setup with a dynamic range of about 50 dB.
