Abstract

MéTODO E SISTEMA DE PESQUISA SìSMICA MARìTIMA. Um método inventivo provê o controle de uma dispersão de pesquisa sísmica enquanto conduzindo uma pesquisa sísmica, a dispersão tendo um navio, uma pluralidade de elementos de controle da dispersão, uma pluralidade de nós de navegação, e uma pluralidade de fontes e receptores. O método inclui a etapa de coletar dados de entrada, incluído dados de navegação para os nós de navegação, estados operacionais de sensores associados com os elementos de controle da dispersão, dados ambientais para a pesquisa, e dados de design da pesquisa. As posições das fontes e receptores são estimadas usando os dados de navegação, os estados operacionais, e os dados ambientais. Trilhas ótimas para as fontes e receptores são determinadas usando as estimativas de posição e uma porção dos dados de entrada que inclui pelo menos os dados de design da pesquisa.Comandos de acionamento são calculados para pelo menos dois dos elementos de controle da dispersão usando as trilhas ótimas determinadas.O método inventivo é complementado por um sistema inventivo.
