摘要：
This paper aims to lay a solid foundation for the application of ultra-wideband (UWB) radio in vehicle environments by exploring the characteristics of UWB channels within a vehicle. A comprehensive measurement campaign was conducted to gather a set of channel impulse responses of UWB links within and outside an armored vehicle. Based on the experimental data, the channel's temporal characteristics, path loss, and capacities are analyzed. The distributions of delay spread and amplitudes of multipath signals are also studied, showing correspondence with the IEEE 802.15.3a UWB channel model. The UWB channels within the vehicle are then modeled by extracting relevant cluster and ray arrival rates and cluster and ray decay factors.
