题目：基于无相位远场数据的反散射问题的数值算法

摘要：In this talk, we consider the inverse problem of reconstructing acoustic obstacles from phaseless far-field data in inverse obstacle scattering. We propose a direct imaging algorithm for reconstruction of an acoustic obstacle, using only phaseless far-field data. Our algorithm does not need to know the type of boundary conditions on the obstacle in advance and is capable to reconstruct multiple obstacles with different boundary conditions and even with different scales. Numerical examples are also provided illustrating that the reconstruction algorithm is stable, accurate and robust to noise. This is a joint work with Dr Haiwen Zhang.
