Abstract

EN LA MEDICION DE DISTANCIA MEDIANTE INICIADORES DE APROXIMACION ULTRASONICO PUEDEN ORIGINARSE IMPULSOS ERRONEOS DE SEÑALES DE PERTURBACION ESTOQUASTICOS QUE PUEDEN SUPRIMIRSE CONTINUAMENTE A TRAVES DE UNA ANCHURA DE PULSACION. EL IMPULSO ERRONEO PUEDE REDUCIRSE YA QUE ES MAYOR QUE EL VALOR QUE LA SEÑAL DE ECO PERMANECE INALTERABLE. EL DEFECTO DEBE ELIMINARSE EN UN PROCEDIMIENTO MEJORADO PARA SUPRIMIR SEÑALES DE PERTURBACION ESTOQUASTICA. EL PROBLEMA SE SOLUCIONA YA QUE LA SEÑAL DE ECO ANCLADA EN EL INICIADOR DE APROXIMACION ULTRASONICO SE EXPLORA EN TIEMPOS DETERMINADOS Y SE TRANSFORMA EL VALOR DE LA EXPLORACION EN VALOR DIGITAL. SE EFECTUA UNA COMBINACION LOGICA MATEMATICA PROGRAMADA DE VALORES DIGITALES CON VALORES DIGITALES ALMACENADAAS EN UNA ACUMULADOR DE DATOS QUE DEDUCE LA SEÑAL DE ECO PRECEDENTE DE VALORES DE EXPLORACION CORRESPONDIENTES. LOS NUEVOS VALORES DIGITALES SUCESIVOS DE LA COMBINACION LOGICA MATEMATICA SE ACUMULA EN UN ACUMULADOR DE DATOS Y ANALIZA LA AMPLITUD Y/O LA ANCHURA DE PULSACION PARA LA DETERMINACION DEL VALOR DE LA DISTANCIA. DE ESTE MODO SE ORIGINAN VALORES DE DISTANCIA PARA CADA CICLO DE IMPULSO QUE SE MUESTRA. EL PROCEDIMIENTO SE EMPLEA EN INICIADORES DE APROXIMACION A DISTANCIA PARA MEDIR DISTANCIAS.
