3-D image reconstruction from near-field coherently scattered waves

This work presents a rigorous mathematical derivation of an effective approximate solution to the near-field 3-D inverse scattering/imaging problem for a system where the coherent signals are transmitted, and the scattered signals are subsequently received at individual transmitters and receivers. Potential applications of this technology include a variety of sub-surface imaging modalities such as: UHF foliage penetrating SAR, ground penetrating radar for land mine detection, and electromagnetic millimeter-wave scanning for concealed weapon detection.
