摘　　要：针对UWB信号的特点,采用时域测量方法,得出了UWB信号时域、频域特性.通过对不同环境测量结果的对比,分析了UWB信号的时延特性和强穿透性,利用Simulink时UWB信号的发射、接收装置及信道模型进行了仿真,仿真结果同实际测量结果的对比也在一定程度上验证了IEEE P802.15.4a信道模型的适用性。The measurement and modeling of Ultra Wide Band(UWB)signal are the key issues in UWB area. The time-domain and frequency-domain characteristics of UWB signal are obtained in this paper By applying the time-domain measurement.At the same time the property of UWB signals penetration is analyzed.The measurements and analysis can be used in indoor localization and communication with UWB technology.The IEEE P802.15.4a channel model is verified with the measurements in this paper.
