Inverse scattering for a random source/potential
A/Prof. Jian-Liang Li

This talk is concerned with the inverse scattering for a random source/potential, where the source/potential is assumed to be microlocally isotropic generalized Gaussian random field such that its covariance operator is a classical pseudo-differential operator. For such a distributional source/potential, we show that the direct scattering problem admits a unique solution in the sense of distribution. For the inverse scattering problem, we demonstrate that the principle symbol of the covariance operator can be uniquely determined with probability one by the high frequency limit of the averaged near-field or far-field data obtained form a single path of the random source/potential.
