Three-Dimensional Microwave Tomography by a 2-D Slice-Based Reconstruction Algorithm

3d Sliced Tomographic Inverse Scattering Experimental Results

“…However, it has been also shown, by numerical examples, that it allows to localize and to roughly retrieve the silhouette of elongated scatterers [12]. But this is just the aim pointed out before.…”

“…Then a thresholding procedure is exploited to curtail spurious artifacts and noise nonsense as described in [12]. Note that the singular system can be calculated once, because it does not depend on the height y m .…”

Processing strategies for high-resolution GPR concrete inspections

“…The raw data were processed using three different strategies: conventional 2-D processing using the horizontal E-field data only followed by the construction of a 3-D dataset for the presentation of the data; full 3-D processing of the datasets collected by the two antennas followed by data fusion during which the two datasets were combined into one dataset [2]; inverse scattering followed by data fusion [9].…”

“…Sbartai et al [7] suggest the use of an artificial neural network for solving the inverse problem related to radar data acquired on reinforced concrete. The application of an inverse scattering algorithm to radar data acquired on reinforced concrete is suggested by Soldovieri et al [8][9][10][11]. In fact, the adoption of a linear inverse scattering approach based on a simplified model of the electromagnetic scattering permits many applicative advantages in terms of fast and effective processing.…”

SAR stereo imaging algorithm based on Capon spectrum estimation

“…Synthetic Aperture Radar (SAR) three-dimensional (3D) stereo imaging has been recently proposed in literatures to allow distinguishing different scattering mechanisms along the elevation direction [1][2][3] , by using multibaseline acquisitions. SAR stereo imaging is the extension of conventional two-dimensional (2D) SAR imaging principle to three dimensions.…”
