To realize image generation in real time with a portable radar system, a uniform diffraction tomographic (UDT) imaging algorithm is proposed to investigate objects buried in planar stratified media. Unlike conventional diffraction tomography (DT), UDT provides smoothly continuous images through layered structures, and like DT, the fast Fourier transform (FFT) is applied to generate images in real...
In this paper, a fast imaging algorithm based on the layered Green's function is applied to generate images of planar stratified media. Imaging results with a gap between blocks inside the wall are analyzed based on different polarizations. 2D FDTD simulations and measurements are used to generate near-field synthetic aperture backscatter data.
