Abstract
La invencion se refiere a un metodo para reducir el ruido armonico en una senal vibrosismica registrada por un sensor, dicha senal vibrosismica corresponde a una secuencia vibratoria dada emitida al menos por una fuente y propagada en una subsuperficie en la cual se refleja; la invencion esta caracterizada porque comprende los siguientes pasos que consisten en (a); correlacionar la senal vibrosismica, o parte de la misma, con una senal que corresponde al componente fundamental de la secuencia de vibraciones emitidas por la fuente; (b) a partir de la senal correlacionada, seleccionar una parte la cual corresponde a la energia del componente fundamental de la senal vibrosismica y aplicar un operador de estimacion del componente armonico de la senal correlacionada a dicha parte selecciona; (c) deducir a partir de ahi una estimacion del ruido armonico de la senal vibrosismica y sustraer dicha estimacion de la senal.
