摘要:

运用结合了扩展手段的非线性对比源反演算法解决二维弹性波矢量情况的成像问题,其中采用的扩展手段为正则化方法和并行频率方法。测量二维实测弹性波数据的实验设置是多收发分置的。以矢量方式对二维实测弹性波数据的重建结果验证了扩展后对比源反演算法的有效性和精确性,是一种非常有前景的解决弹性波成像问题的处理方法。

Abstract:

The nonlinear contrast source inversion algorithm combined with extended approaches, such as the regularization and concurrent frequency(CF) approaches, is applied to solving the vector case of two-dimensional elastic wave imaging problems. The experimental data are measured in the multibistatic mode. The inversion results of the vector case prove the capability and the accuracy of the extended CSI algorithm,which is a promising scheme for the elastic wave imaging.
