In this paper the capability of differentiating surfaces with different roughness characteristics by using bandwidths practical with low TeraHertz (low-THz) devices is discussed. The results presented show that the measured variance from a surface with random surface scatterers decreases as the bandwidth of a transmitted signal increases which allows additional classification of directly illuminated rough surfaces. These findings presented will allow more information to be extracted from images obtained in complex environments whilst keeping the processing complexity low.
