Inverse scattering with multi-frequency sparse data
Speaker

Abstract

In this talk, we will introduce a direct sampling method for inverse scattering problems, which uses multi-frequency backscattering far field data taken at sparse directions. The underlying object could be point-like scatterers, small scatterers, or extended inhomogeneities and obstacles. Both the theoretical basis and numerical simulations will be presented.
