Abstract

codificação de fonte e separação de fonte simultâneas como uma solução prática para inversão de campo de onda completa. trata-se de um método para inversão de campo de onda completa simultânea de famílias de dados geofísicos codificados de fonte (ou receptor) para determinar um modelo de propriedades físicas (118) para uma região sub-superficial, especialmente adequada para levantamentos onde as condições de geometria de receptor fixa não foram satisfeitas na aquisição de dados. a separação de fonte simultânea (104) é realizada para diminuir qualquer efeito dos dados geofísicos medidos que não satisfaçam a suposição de receptor fixo. um etapa de processamento de dados (106) após a separação de fonte simultânea atua para conformar os dados simulados de modelo (105) aos dados geofísicos medidos (108) para combinações de fonte e receptor que sejam faltantes nos dados geofísicos medidos.
