声学反边值问题的一种非迭代重建算法

A Non-Iterative Reconstruction Algorithm for the Acoustic Inverse Boundary Value Problem

Tianyu Yang, Yang Yang

摘要:

我们提出了一种非迭代算法来重建各向同性的声波速度从测量的Neumann-to-Dirichlet映射。该算法是基于边界控制方法设计的,并且只涉及稳定的计算。我们证明了算法的收敛性,并给出了其数值实现。在恒速和变速两种情况下,在全边界测量和部分边界测量以及不同噪声水平下,验证了该算法的有效性。

英文摘要:

We present a non-iterative algorithm to reconstruct the isotropic acoustic wave speed from the measurement of the Neumann-to-Dirichlet map. The algorithm is designed based on the boundary control method and involves only computations that are stable. We prove the convergence of the algorithm and present its numerical implementation. The effectiveness of the algorithm is validated on both constant speed and variable speed, with full and partial boundary measurement as well as different levels of noise.
