摘　　要：超宽带(UWB)通信系统因为其良好的抗多径性,及比较高的传输速率引起越来越多的科研人员的研究兴趣。射线跟踪是一种被广泛应用于移动通信和个人通信环境中预测无线电波传播特性的技术,它同样适用于研究室内UWB无线信道的特征,能够提供精确度较高的预测结果。本文采用SBR/Image这种射线跟踪技术对UWB信号的传播特性进行了研究,利用MATLAB语言实现了上述算法,并结合相关文献对特定的室内视距环境进行仿真及数据分析,计算结果与文献结果吻合良好,表明本文方法是正确有效的。Ultra-wideband （UWB） communication systems have drawn more and more attention due to its merits such as high data rate and anti-multi-path performance. As is well known, ray trace method is popular method for radio propagation link prediction in wireless communications, and it is also effective for UWB radio channel modeling. In this thesis, one of the ray trace methods, Shooting-and-Bouncing Ray/Image （SBR/Image）, has been employed to study the propagation characteristics of UWB signals. The above algorithm is carried out by employing MATLAB tools, and the simulated results are compared with other results in reference. The well accordance between these results show that the method proposed in this thesis is correct and effective.
