摘要：In this talk, we will present a framework for the proof of a priori bounds explicitly with respect to frequencies for random surface scattering problems. By introducing a variable transform, the variational formulation in a random domain is reduced to that in a definite domain with random medium. Combining the stability result for the deterministic case, Pettis measurability theorem and Bochner’s Theorem further yield the stability for random scattering problems. Besides, an MCCUQ reconstruction method is proposed for solving the inverse random surface scattering problem. Numerical results will demonstrate the reliability and efficiency of the proposed method.
