RF Tomography in Free Space: Experimental Validation of the Forward Model and an Inversion Algorithm Based on the Algebraic Reconstruction Technique
Figure 3
The figure shows reconstruction from simulated scattered electric fields, for an empty PVC pipe. TSVD (a) offers reconstruction very similar to ART (b), but the best image is obtained by using ART with the introduction of physical bounds (c). Both (b) and (c) have been obtained with . All images have been normalized to their maximum since quantitative reconstruction is not of interest.
