本文利用特征线方法, 对均匀层状弹性介质同时进行震源函数与介质波阻抗反演, 通过数值试算结果表明, 震源函数和波阻抗的理论值与反演值十分吻合。方法简便、有效, 并具有一定的抗干扰能力。

The shot function and wave impedance of homogeneously layered elastic media are inversed simultaneously via characteristic curve method in this paper. Numerical experiments show that the theoretical values of the shot function and wave impedance are matched well with the inversed ones. And the method is easy to implement and can resist noise to a certain degree.
