Low-THz rough surface imaging

In this paper the potential advantages of imaging outdoor environments in the low Terahertz (low-THz) range of frequencies (0.1 THz-1 THz) are discussed, in terms of the device parameters available at these frequencies and also in terms of the scattering expected by THz waves propagating in real-world environments. The results presented confirm that imaging surfaces with surface characteristics similar to those found in outdoor environments, with low-THz devices, aids in the interpretation of the obtained image whilst keeping the image processing complexity low.
