A new regularization approach applied to electromagnetic inverse scattering in 3D

We develop a new regularization approach for 3D quantitative microwave tomography, based on a discontinuity adaptive model. The resulting reconstructions from sparse data points for 3D piecewise constant objects are encouraging. The reconstructions …

Quantitative microwave tomography from sparse measurements using a robust huber regularizer

In statistical theory, the Huber function yields robust estimations reducing the effect of outliers. In this paper, we employ the Huber function as regularization in a challenging inverse problem: quantitative microwave imaging. Quantitative …
