摘要
从半空间的 SH 波方程出发,得到均匀介质背景下的非线性反演积分方程。利用矩量法离散积分方程,并采用正则化 Born 迭代方法,最终完成非线性反演过程。数值模拟计算部分结合适当的改进方案给出了令人满意的结果。
An nonlinear inverse integral equation is obtained starting with the SH elastic wave equation in homogenous medium in half space.The moment method and the regularized Born interative methods are presented to solve the nonlinear inverse problem. Also,some suggestions are given to get better results.The numerical results show high accuracy and steability.
