We investigated an inverse imaging problem by applying the Rytov approximation for Through-the-Wall Imaging using THz waves. In the beginning, we studied some properties of THz waves and the physical conditions for THz imaging in matter. Then we started with Maxwell's equations to derive a model for the transmission of Green's functions and used a Lippman-Schwinger integral equation and Rytov approximation to predict the scattered field. We applied the L-curve method for the selection of regularization parameters, and then presented the reconstruction algorithm and illustrated the result with numerical simulations. We also compared this result to the one obtained by the Born approximation. http://archive.org/details/thzimagingthroug109453739 Korea Navy author.
