基于线性采样法的局部粗糙界面及掩埋物体的近场成像(张波)
2022-09-09 | 编辑:

  Consider the inverse acoustic scattering of time-harmonic point sources by a locally perturbed interface with buried obstacles in the lower half-space. A novel version of the sampling method is proposed to simultaneously reconstruct the local perturbation of the rough interface and buried obstacles by constructing a modified near-field equation associated with a special rough surface, yielding a fast imaging algorithm. Numerical examples are presented to illustrate the effectiveness of the inversion algorithm.
