Abstract

SE PROPORCIONA UN APARATO DETECTOR DEL NIVEL ACUSTICO, EN EL CUAL LOS IMPULSOS DE LA ENERGIA ACUSTICA SON TRANSMITIDOS MEDIANTE UN TRANSDUCTOR CARGADO ELECTRICAMENTE HACIA UNA SUPERFICIE A DETECTAR, Y LA SALIDA ELECTRICA DEL TRANSDUCTOR QUE SIGUE AL IMPULSO RECIBIDO POR UN RECEPTOR ES DIGITALIZADA Y ANALIZADA POR UN MIRCROPROCESADOR PROGRAMADO PARA DETECTAR UN ECO DESDE LA SUPERFICIE PARA PRODUCIR UN PERFIL DIGITALIZADO DEL ECO. EL PERFIL DEL ECO DIGITALIZADO ES INCREMENTADO EXTRAYENDO CRESTAS ANGOSTAS QUE CON TODA PROBABILIDAD CORRESPONDEN CON CIERTO TIPO DE ECO ESPUREO (ELIMINAR_ECOS_ANGOSTOS_F0), Y VALLES ANGOSTOS QUE REPRESENTAN LA FRAGMENTACION DE UN ECO DESEADO (REFORMAR_ECOS_FRAGMENTADOS_F0). LOS ECOS SON IDENTIFICADOS COMPARANDO EL PERFIL CON UN UMBRAL DE VARIACION TEMPORAL GENERADO DERIVADO DE UNA REGRESION LINEAL REALIZADA EN PARTE DEL PERFIL DE ECO (UMBRAL_DE_VARIACION_TEMPORAL_EN_F2), SIENDO EFECTUADOS VARIOS TIPOS DIFERENTES DE COMPARACION Y SUS RESULTADOS COMBINADOS (ALF_ALGORITMO) ANTES DE SELECCIONAR EL ECO CON MAYOR PROBABILIDAD DE SER VERDADERO EN BASE A LOS RESULTADOS COMBINADOS (SELECCIONAR_MEJOR_ECO_DE_FICHERO_3).
