3D Quantitative imaging of a complex shape target from microwave scattering measurements

Abstract

We propose a quantitative reconstruction of an aggregate of spheres from microwave experimental data. A joint work between the inversion developments and the experimental ones has been necessary to image accurately this complex shape target. Indeed, the current target is an assembly of very small particles with respect to the wavelength. The challenge was both to be able to measure its scattered field and to retrieve its intrinsic details. In particular, we took into account the real random noise with a Bayesian formulation.
