Abstract: A new computing method is proposed for solving inverse problem of one-dimensional wave equation on seismic prospection by using difference-discrete regularization method. The numerical results of simulation are given and show the method is faster convergence and more powerful noise-resistance.

Key words: wave equation, inverse problem, regularization, ill-posed
