The Born-iterative method (BIM) and the distorted-Born-iterative method (DBIM) have been proposed and verified as methods of solving the nonlinear inverse scattering problem for dielectric scatterers. The continuous-wave (CW) implementation of the DBIM was recently used to process microwave scattering data. Previously, diffraction tomography was used to process the data (a microwave image of human arm), resulting in an image with a small dynamic range due to the high contrasts present in the human body. Using the DBIM, the processed image was significantly improved. It is seen that upon iterating with DBIM, the contrast of the image is drastically enhanced.
