论文摘要
在这项工作中，我们为电磁反射问题提供了一种新型的线性迭代解决方案，该解决方案具有无相相的数据，可用于强烈散射，有损培养基。它基于扩展的Rytov近似，可显着扩大常规Rytov近似的有效性范围。通过修改此扩展，并将其包括在扭曲的波浪迭代公式中，可以获得可以获得介电常数的实际和虚构成分的准确重建结果。我们将该技术表示为扭曲的波浪扩展无量rytov迭代方法（DXPRIM），并提出其推导和数值公式。使用仿真和实验示例，我们证明了DXPRIM可以使用无量的测量数据重建强大的散射器，并表明它的表现优于最先进的无相相技术。
In this work we present a novel linear iterative solution to an electromagnetic inverse scattering problem with phaseless data for strongly scattering, lossy media. It is based on an extended Rytov approximation that significantly widens the validity range of the conventional Rytov approximation. By modifying this extension and including it in a distorted wave iterative formulation, accurate reconstruction results for both the real and imaginary components of permittivity can be obtained. We denote the technique as the distorted wave extended phaseless Rytov iterative method (DxPRIM) and we present its derivation and numerical formulation. Using simulation and experimental examples, we demonstrate that DxPRIM can reconstruct strong, lossy scatterers with phaseless measurement data and show that it outperforms state-of-the-art phaseless techniques.
