The imaging of dielectric targets hidden behind a wall is addressed in this paper. 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.
本文探讨了隐藏在墙壁后面的电介质目标的成像问题。提出了一种用于快速准确计算目标向前散射场的解析求解器，该求解器考虑了电磁场与墙壁界面的所有相互作用。此外，还引入了一种能够解决完全潜在的非线性逆散射问题的反演程序。该技术利用勒贝格空间中的正则化方案来重建隐藏目标的图像。提供了初步的数值结果，以便初步评估所开发求解器的能力。
