Abstract :
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° 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.
