The proposed computationally efficient technique allows the reconstruction of detailed images of scattering objects. Transmissions as well as reflection imaging modalities in the near-field and far-field were investigated. In this study, we implemented the FDTD-TR algorithm in three dimensions using time-reversed convolutional perfectly matching layers as boundaries to truncate the simulation domain. The method works for dielectric as well as conducting objects. The methods capabilities in imaging multiple objects and behind-the-wall imaging are also presented. © 2014 © 2014 Taylor & Francis.EnglishFinite difference time domain methodImage matchingImage reconstructionTime domain analysisComputationally efficientConducting objectsFinite difference time domain techniqueFinite-difference time-domain (FDTD) methodsMicrowave imagingScattering objectsSimulation domainTime-reversalImaging systemsArticle10.1080/09205071.2014.929048
