Imaging of objects buried in a finite-sized dielectric background

The authors propose a simple algorithm to reconstruct the image of objects embedded in a finite-sized dielectric background. The algorithm is based on the concept that an undistorted image may be reconstructed if the true range profiles of the embedded object can be obtained. Neglecting the phenomena of multiple reflections and the bending effect of wave propagating in the dielectric, they propose a simple algorithm to compensate the electrical length of the wave traveling in the dielectric. Although the assumptions made are not precise, nevertheless, experimental results show that the proposed method is very time-efficient, and is effective in reconstructing a recognizable image of the object embedded in a background having moderate dielectric constant and smooth air-dielectric boundary shape
