UltraWideband wireless channel in presence of atmospheric gases and refined engine oil

In this study we propose using Ultra Wideband Channel measurements to detect the presence of different substances between the antennas. This technique takes advantage of the large number of frequencies which an Ultra Wideband signal occupies. We propose two methods to detect differences in channel magnitude frequency responses when in the presence of different substances between the transmitting and receiving UWB antennas. We then take preliminary measurements and fit a curve of best fit to the processed data. The preliminary results indicate that this technique may be able to be used in conjunction with data mining techniques to detect the presence of different substances between the antennas. This potentially provides a non-destructive technique to measure different substances in the wireless medium between the two UWB antennas.
