Abstract :
This communication is concerned with the performance achievable within a 3-D inverse scattering approach in relationship with the measurement configuration. The problem is undertaken under the Born approximation, and three configurations are considered, namely a multimonostatic, a single view/multistatic and a multiview/multistatic, all of them in the multifrequency framework. The analysis is worked out with the tools of the diffraction tomography and of the singular value decomposition of the relevant operator. Tomographic reconstructions based on full-wave synthetic data are shown.
