英文摘要 | Abstract We propose a direct imaging method based on reverse-time migration in order to reconstruct extended obstacles in the half space with finite aperture elastic scattering data at a fixed frequency. We demonstrate the resolution of the reconstruction method in terms of the aperture and the depth of the obstacle embedded in the half space. The resolution analysis is studied via the point spread function and implies that the imaginary part of the cross-correlation imaging function always peaks on the upper boundary of the obstacle. Numerical examples are included to illustrate the effectiveness of the method. |
