Abstract

METODO DE CAPTACION DE DATOS MARINOS Y TRATAMIENTO DE DATOS. CONSISTE EN UNA FUENTE SISMICA MOVIL (14) QUE PRODUCE UN IMPULSO DE ONDA ACTISTICA, UN DETECTOR (16) REMOLCADO QUE INCLUYE UNA CADENA DE HIDROFONOS (18A, 18B, 18X), CON MEDIOS DE FLOTABILIDAD ASOCIADOS, QUE DETECTAN REFLEXIONES PRIMARIAS Y REFLEXIONES FANTASMAS EN CADA UNO DE ELLOS. EXISTEN MEDIOS QUE CORRIGEN LAS REFLEXIONES PRIMARIAS RESPECTO A UN ORIGEN, REUNEN LAS SEÑALES EN REGISTROS DE PUNTOS DE PROFUNDIDAD COMUN, APLICAN CORRECCIONES DE DESPLAZAMIENTO NORMAL Y DESALINEAN LAS REFLEXIONES FANTASMAS, DESTACANDO POR TANTO LAS REFLEXIONES PRIMARIAS.
