We consider a problem of estimation of the parameters of a seismic signal based on real observed data. For this purpose, we propose a new mathematical model that reduces the task to a nonlinear, nonsmooth, nonconvex minimization problem. Using a special structure of the signal, we also propose a numerical algorithm of finding the solution of the optimization problem. Our method is based on the combination of the Levenberg–Marquardt algorithm and a simulated annealing type approach. We show the convergence of the algorithm and discuss the practical implications, which lie in a good compatibility with real seismic data, and the applicability to experiments.
