Abstract

MéTODO PARA ANALISAR TRAçOS COLETADOS AO LONGO DE UMA PLURALIDADE D ELINHAS DE VARREDURA EM UMA áREA DE PESQUISA SìSMICA MARINHA E ARTIGO. A presente invenção provê um método para reduzir diferenças de tempo de reflexão de fundo de água. O método inclui selecionar uma pluralidade de grupos de traço, cada traço tendo um deslocamento a partir de um ponto médio e um tempo de reflexão de fundo de água. O método também inclui determinar uma taxa de mudança do tempo de reflexão de fundo de água de cada traço e gerar uma velocidade de água modelo e um tempo de reflexão de fundo de água modelo para cada ponto médio de traço usando uma função pré-selecionada dos tempos de reflexão de fundo de água e as taxas de mudança. Adicionalmente, o método inclui gerar uma pluralidade de correções de tempo de reflexão de fundo de água para os traços em cada grupos de traço usando uma função pré-selecionada dos tempos de reflexão de fundo de água, os tempos de reflexão de fundo de água modelo, velocidades de água modelo, e os deslocamentos de traço.
