Abstract

LA INVENCION SE REFIERE A LA MEDICION DE DISTANCIA POR ECO DE IMPULSOS Y EN PARTICULAR A UN METODO Y UN APARATO PARA CALCULAR TAL DISTANCIA DETECTANDO REFLEXIONES MULTIPLES DE UNA SEÑAL DE IMPULSO DADA. AL DETECTAR MULTIPLES REFLEXIONES, Y NO UNICAMENTE EL ECO PRIMARIO LOS RETARDOS DE TIEMPO INTERNOS QUE DE OTRO MODO PROVOCARIAN ERRORES SISTEMATICOS PUEDEN SIMPLEMENTE ELIMINARSE Y LAS MULTIPLES LECTURAS OBTENIDAS PUEDEN UTILIZARSE PARA OBTENER VERIFICACIONES DE AUTODIAGNOSTICO DEL SISTEMA, ELIMINAR LA INFORMACION FALSA Y OBTENER UNA MEDICION PRECISA DE UNA DISTANCIA. UNA VENTAJA PARTICULAR DEL METODO ES QUE SE PUEDEN MEDIR DISTANCIA MUY PEQUEÑAS ENTRE EL DETECTOR Y LA DIANA.
