摘要
本文提出了声波方程反演的GR方法。GR法是一种通用的波动方程反演方法,它不受空间维数与边界条件的限制,适应于各类波动反问题。文中导出了算法的基本公式,并给出了一维与二维声波反问题的数值算例,结果表明该算法是一种高精度的稳定算法。
The gradient regularization method for numerical inversion of acoustic wave equation is recommended here. It is a usual method for wave equation inversion. The method is not limited by the dimension or boundary condition, and applies to all wave inverse problems. This article describes the basic formula of the method,and the numerical examples of 1D and 2D acoustic wave inverse problems. The method is proved to be accurate and stable.
