英文摘要: |
This paper is concerned with the inverse problem to determine the shape of multiple three-dimensional obstacles from the knowledge of the limited aperture near-field measurements of the scattered waves for acoustic point source fields.A simple fast algorithm for solving the inverse problem is proposed.Some numerical examples are given showing that the scheme is efficient and practical. |
