An analytical solver for a fast and accurate computation of the forward scattered field by the targets is proposed, which takes into account all the interactions of the electromagnetic field with the interfaces of the wall. Furthermore, an inversion procedure able to address the full underlying non-linear inverse scattering problem is introduced. This technique exploits a regularizing scheme in Lebesgue spaces in order to reconstruct an image of the hidden targets. Preliminary numerical results are provided in order to initially assess the capabilities of the developed solvers.<\/jats:p>","DOI":"10.3390\/s20102865","type":"journal-article","created":{"date-parts":[[2020,5,18]],"date-time":"2020-05-18T11:34:14Z","timestamp":1589801654000},"page":"2865","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["Through-the-Wall Microwave Imaging: Forward and Inverse Scattering Modeling"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6636-1448","authenticated-orcid":false,"given":"Alessandro","family":"Fedeli","sequence":"first","affiliation":[{"name":"Department of Electrical, Electronic, Telecommunications Engineering, and Naval Architecture, University of Genoa, 16145 Genoa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matteo","family":"Pastorino","sequence":"additional","affiliation":[{"name":"Department of Electrical, Electronic, Telecommunications Engineering, and Naval Architecture, University of Genoa, 16145 Genoa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2482-8606","authenticated-orcid":false,"given":"Cristina","family":"Ponti","sequence":"additional","affiliation":[{"name":"Department of Engineering, \u201cRoma Tre\u201d University, via Vito Volterra 62, 00146 Rome, Italy"},{"name":"National Interuniversity Consortium for Telecommunications, Roma Tre University, 00146 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5291-462X","authenticated-orcid":false,"given":"Andrea","family":"Randazzo","sequence":"additional","affiliation":[{"name":"Department of Electrical, Electronic, Telecommunications Engineering, and Naval Architecture, University of Genoa, 16145 Genoa, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8890-2601","authenticated-orcid":false,"given":"Giuseppe","family":"Schettini","sequence":"additional","affiliation":[{"name":"Department of Engineering, \u201cRoma Tre\u201d University, via Vito Volterra 62, 00146 Rome, Italy"},{"name":"National Interuniversity Consortium for Telecommunications, Roma Tre University, 00146 Rome, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,5,18]]},"reference":[{"key":"ref_1","unstructured":"Amin, M.G.
