Abstract

a presente invenção refere-se a um método de resolução de um problema inverso geofísico para estimar um parâmetro físico, o método compreendendo prover um vetor modelo que representa o parâmetro físico, transformar o vetor modelo através de um primeiro operador para prover um primeiro vetor modelo transformado, resol-ver o problema inverso para o primeiro vetor modelo transformado para prover uma primeira solução, transformar o vetor modelo através de um segundo operador para produzir um segundo vetor modelo transformado, resolver o problema inverso para o segundo vetor modelo transformado para prover uma segunda solução, calcular uma soma ponderada da primeira solução e da segunda solução.
