Computational Methods for Estimation of Parameters in Hyperbolic Systems

摘要

Approximation techniques for estimating spatially varying coefficients and unknown boundary parameters in second order hyperbolic systems are discussed. Methods for state approximation (cubic splines, tau-Legendre) and approximation of function space parameters (interpolatory splines) are outlined and numerical findings for use of the resulting schemes in model 'one dimensional seismic inversion' problems are summarized.
