Abstract

de acordo com uma modaliodade é fornecido um método para corrigir dados sísmicos registrados em que cada relógio de receptor é potencialmente impreciso. visto que o campo de onda sísmica não é aleatório e contém eventos coerentes que são registrados por todos os receptores em uma área local, é possível estimar as diferenças na referência de tempo comparando-se os registros dos receptores diferentes em uma área local. sem nenhuma referência de tempo externa, sinal de tempo ou traço piloto, uma totalidade dos próprios dados sísmicos pode ser usada para determinar como cada relógio do receptor desvia do tempo real.
