摘要 基于广义反射透射系数矩阵正演方法 ,讨论了层状介质的声波波动方程反问题 .推导出波数频率域中的雅可比矩阵的解析表达式 ,其计算在正演过程中求出 .采用最小二方法可得到层介质参数 .数值结果表明反演方法的正确有效性 . Based on the generalized reflecton and transmissiom method,we discuss waveform inversion of acoustic wave equation in layered media. We derived analytical expression of Jacobian matrix in frequency wavenumber domain which can be computed directly from forward modeling. The iversion is performed by using least squares technique. Numerical examples prove the feasibility of the method.
