Popis: | In this paper, UWB polarization measurements with a multipath decomposition process is studied with an array of propagation measurements using three receiving antenna orientations. In order to estimate each of the decomposed impinging electric field at a receiving location in the multipath channel, a modified version of the sensor-CLEAN algorithm is applied to the array measurements in combination with the estimation method. The fidelity of the combined estimation process with array measurements is verified by comparison between the measured and estimated signal waveforms for a reoriented receiving antenna. |
