Abstract

EL SECTOR TECNICO DE LA INVENCION ES EL DE LOS DISPOSITIVOS DE PROTECCION CONTRA EL RUIDO Y OTRAS ONDAS ACUSTICAS, CUYA APLICACION PRINCIPAL ES EL CAMPO SUBMARINO. EL PROCEDIMIENTO DE DETECCION ACUSTICA SEGUN LA INVENCION ES TAL QUE: - SE COLOCA AL MENOS UN DETECTOR DE VIBRACION (7 1 DIRECTAMENTE EN AL MENOS UNA FUENTE DE RUIDO (1 1 ) PARASITO DE BAJAS RELACIONES SEÑAL RUIDO, DEL QUE SE TOMA ASI LA SEÑAL DESDE SU ORIGEN Y SE TOMA ENTONCES COMO SEÑAL DE REFERENCIA, Y SE RETIRA (9) LA PARTE DE LA SEÑAL TOMADA POR UNA ANTENA (2) DE MEDICION DE PRESIONES ACUSTICAS ASOCIADA A UNA UNIDAD (10) DE TRATAMIENTO DE LA SEÑAL Y QUE SE CORRELACIONE CON DICHA SEÑAL PARASITA DE REFERENCIA. - SE ASOCIA EL SOPORTE (20) DE DICHA ANTENA (2) A UN SISTEMA (4,5,8) DINAMICO DE CONTROL DE MOVIMIENTO QUE ESTA GESTIONADO POR LA SEÑAL TOMADA POR CUALQUIER DETECTOR DE ERROR (6) SOLIDARIO AL SOPORTE DE LA ANTENA (2) PARA QUE SEA MINIMA - SE DETERMINAN ENTONCES (10) LAS CARACTERISTICAS DE CUALQUIER OTRA POSIBLE FUENTE EXTERIOR ACUSTICA NO CONOCIDA.
