內(nèi)容摘要：
This talk is concerned with the inverse acoustic scattering problem with phaseless total-field data at a fixed frequency. An approximate factorization method is developed to numerically reconstruct both the location and shape of the unknown scatterer from the phaseless total-field data generated by incident plane waves at a fixed frequency and measured on the circle with a sufficiently large radius. The theoretical analysis of our method is based on the theory of oscillatory integrals. To the best of our knowledge, this is the first attempt to develop a factorization type method for inverse scattering problems with phaseless data.
