Abstract: This paper mainly focuses on one-dimensional wave equation of the deep seismic exploration. It researches the problem with Laguerre spectral method, and gives the discrete process for the solution, then it carries on the parameter inversion with the Gauss-Newton method together with the numerical simulation through the simulation. The result indicates that this method has a good effect on the deep seismic exploration.

Key words: seismic exploration, one-dimensional wave equation, Laguerre spectral method, Gauss-Newton method
