2-D Image Reconstruction from Microwave Scattering Data

摘要

The microwave imaging based on the diffraction tomography and the interpolation methods has been studied. Three interpolation methods, the nearest-neighbor, bilinear, and bi-sinc, are chosen to increase imaging accuracy and efficiency. Different transformations between rectangular and polar-like coordinates are presented. The reconstruct results show that the introduced bi-sinc interpolation method consumes less time and gets more accurate image.
