【 摘 要 】

The problem of through-the-wall imaging is considered. A numerical method for Maxwell's Equations is developed and implemented with the goal of generating an approximate solution to this problem. The forward problem is solved using the Yee Scheme, and this solver is used in the inverse problem of detecting and analyzing objects inside a room, with no direct vision of the inside. It is shown how different sizes and shapes of objects have different responses to source waves, and these differences can be used to approximate the object. Numerical results show that this reconstruction procedure gives an accurate approximation to the boundary of the object. (C) 2016 Elsevier Inc. All rights reserved.
