摘要

本文讨论了散射问题，特别是差分微波成像问题的非线性程度问题。DNL的量化是为了评估Born一阶(线性)近似的有效范围。因此，这是一种评估微波成像中正反散射问题难度的方法。考虑了几个具有不同dnl的3D dMWI示例来说明所提出的推导的兴趣。

On the born approximation for differential microwave imaging using volume integral equation formulation

The Degree of Non-Linearity (DNL) of scattering problems and specifically of differential Microwave Imaging (dMWI) problems is addressed in this paper. The quantification of the DNL amounts to evaluate the validity range of the Born first order (linear) approximation. It is therefore a way to assess the difficulty of both forward and inverse scattering problems arising in Microwave Imaging. Several examples of 3D dMWI with various DNLs are considered to illustrate the interest of the proposed derivation.
