Comparing Two Approaches for Point-Like Scatterer Detection

الملخص EN

Many inverse scattering problems concern the detection and localisation of point-like scatterers which are sparsely enclosed within a prescribed investigation domain.

Therefore, it looks like a good option to tackle the problem by applying reconstruction methods that are properly tailored for such a type of scatterers or that naturally enforce sparsity in the reconstructions.

Accordingly, in this paper we compare the time reversal-MUSIC and the compressed sensing.

The study develops through numerical examples and focuses on the role of noise in data and mutual coupling between the scatterers.
