FERNANDEZ-BERDAGUER, E. M.; PEREZ, L. V. e SANTOS, J. E.. Numerical experiments on parameter estimation in acoustic media using the adjoint method. Lat. Am. appl. res. [online]. 2002, vol.32, n.4, pp.307-313. ISSN 0327-0793.
We present an algorithm to solve the problem of estimation of the wave speed in a layered acoustic medium. It is based on the adjoint method. Even though it is a fast algorithm, it is able to detect approximately the interfaces and estimate the amplitudes of the speed parameter. Numerical examples illustrate the application of the algorithm in seismic inversion.
