摘　　要：时域射线跟踪方法是研究超宽带信号传播特性的有效技术。文中基于时域一致性绕射方法研究室内复杂环境中的超宽带信号传播特性。最后利用Wireless Insite软件对室内复杂环境超宽带信号的直射、反射和绕射等多径传播特性进行了仿真分析,得到功率延迟分布等多径传播特性。The method of time-domain ray tracing is an efficient technology to investigate the propagation characteristics of uhra-wideband （UWB） signal. In this paper, the propagation characteristics of UWB sig- nal in indoor complex environment are studied based on TD-UTD. The direction, reflection and diffraction of UWB signal are studied in indoor complex environment using the software of Wireless Insite. Finally, the muhipath propagation characteristics such as power delay distribution are obtained.
