反演一维声阻抗的Sondhi-Gopinath法

Sondhi-Gopinath Method for the Inverse One-Dimension Acoustic Impedance

作者从一维波动方程反问题的数学模型出发 ,经拉氏变换 ,根据 Sondhi- Gopinath法 ,导出了分布参数系统一维声阻抗反问题的解析式。该解是一个称为脉冲响应参量的函数 。

In this paper, an analytic solution of the acoustic impedance to one dimensional elastic wave equation is derived by using the Sondhi Gooinath approach with a Laplace transform. A function of the so called impulse response, the solution may be evaluated based upon wave field on the earth surface with displacement velocity.
