Abstract

recuperação de sinal durante a separação e decomposição de fonte simultânea. um dispositivo pode incluir um processador que pode recuperar os sinais mal alocados no processo de decomposição de dados sísmicos adquiridos com fontes simultâneas. o processador pode atualizar a estimativa de sinal primário com base, pelo menos em parte, em uma operação de separação que separa os sinais de coerência dos sinais de ruído em uma saída associada com o resíduo determinado como sendo energia restante para separação. o processador pode ser incorporado na estimativa de sinal primário iterativa do processo de decomposição ou ser aplicado para a saída de decomposição preexistente. em resposta à satisfação de uma condição final, o processador pode transmitir uma saída decomposta que inclui os sinais de coerência fracos recuperados da má alocação ou erro na estimativa de sinal primário. o processador também pode transmitir a saída decomposta para uso na geração de uma imagem sísmica. a imagem sísmica pode representar hidrocarbonetos em uma região subterrânea da terra ou perigos de perfuração subterrânea.
