Abstract

"MéTODO PARA A SUPRESSãO DE REFLEXõES MULTIPLAS DE DADOS SìSMICOS MARìTIMOS". é descrito um método para a supressão de reflexões múltiplas usando um algoritmo de Kirchhoff. O método permite a simulação de múltiplas de superfície livre a partir de uma seção de afastamento nulo ou de entrada. As etapas do método compreendem: i) simulação de reflexões múltiplas por meio de uma soma do tipo Kirchhoff aplicada a uma seção de pseudo afastamento nulo; ii) aplicação de um filtro adaptativo para ajustar a múltipla simulada e iii) subtração da múltipla simulada ajustada assim obtida dos dados de entrada.
