Abstract
SE DESCRIBE UN METODO, UN PROGRAMA DE ORDENADOR Y UN APARATO PARA LA IDENTIFICACION DE SENALES REFLEJADAS CON POSTERIORIDAD A SU REFLEXION DENTRO DE UN MEDIO. EL METODO COMPRENDE LA OBTENCION DE SENALES DE RETORNO (100), QUE RESULTAN A PARTIR DE MEDICIONES QUE SE REALIZAN DURANTE UN PERIODO DE MEDICION. EL PERIODO DE MEDICION COMPRENDE SUBPERIODOS, COMPRENDIENDO LAS SENALES DE RETORNO SENALES REFLEJADAS Y RUIDO. LA PLURALIDAD DE SENALES DE RETORNO SE DIVIDEN EN CONJUNTOS PLURALES (220) DE IGUAL CARDINALIDAD O TAN IGUALES COMO SEA POSIBLE DE TAL MANERA QUE SU CARDINALIDAD NO DIFIERA EN MAS DE UNO. UN VALOR DE CORRELACION APILADO SE DETERMINA (130) PARA LAS SENALES DE RETORNO MEDIANTE LA DETERMINACION DE LA MEDIA DE LAS SENALES DE RETORNO A TRAVES DE LOS CONJUNTOS PLURALES (230) Y DETERMINANDO UN VALOR DE CORRELACION DE LOS CONJUNTOS PLURALES A LO LARGO DE CADA UNO DE LOS SUBPERIODOS DE TIEMPO (240). LOS PICOS EN LA VARIACION DEL VALOR DE CORRELACION APILADO A LO LARGO DEL TIEMPO PUEDEN SER IDENTIFICADOS A CONTINUACION Y CADA UNO DE LOS PICOS DE LA VARIACION DEL VALOR DE CORRELACION APILADOS A LO LARGO DEL TIEMPO SE PUEDE ATRIBUIR A UNA SENAL REFLEJADA
