A highly efficient iterative approach for inverse acoustic obstacle scattering problems in three dimensions
Zhiyong Cheng, Heping Dong, Lu Zhao
This paper concerns a three-dimensional inverse acoustic obstacle scattering problem from scattered field or phased/phaseless far-field data. Based on the boundary integral defined…
