本文介绍了在消声室的实验结果，评估的UWB信道探测系统的可靠性的基础上确定性的方法与SAGE算法。该系统可以分辨和检测角域中10/spl度/的分离波，这接近分辨率极限。在延迟域中，可以分辨出相隔0.67 ns的波，其中发现了子带带宽与谱估计之间的关系。检测入射波的算法的行为是在分辨率限制内进行了检查。采用球面入射波模型估计入射波的参数。与平面波模型相比，该模型可以大大减少寄生路径的数量。
The paper presents the results of experiments in an anechoic chamber that assessed the reliability of a UWB channel sounding system based on a deterministic approach with a SAGE algorithm. The system could resolve and detect waves separated by 10/spl deg/ in the angle domain, which was near the resolution limit. In the delay domain, waves separated by 0.67 ns could be resolved where the relation between the bandwidth of the subband and spectrum estimation was discovered. The behavior of the algorithm for the detection of incident waves which are within the resolution limit was examined. The spherical incident wave model was applied for estimating the parameters of incident waves. This model could drastically reduce the number of spurious paths compared to the plane wave model.
