Abstract

SE DESCRIBE UN APARATO PARA SEGUIMIENTO DE LA FRECUENCIA RESONANTE VARIABLE DE UNA ESTRUCTURA ELECTRICAMENTE RESONANTE, CARACTERIZADO POR: UN OSCILADOR DE FRECUENCIA VARIABLE QUE PROPORCIONA UNA SEÑAL DE EXCITACION DE FRECUENCIA VARIABLE, QUE ABARCA LA POSIBLE GAMA DE FRECUENCIAS RESONANTES DE LA CITADA ESTRUCTURA RESONANTE, UNA LINEA DE TRANSMISION BIDIRECCIONAL DE RF QUE CONECTA DICHO OSCILADOR DE FRECUENCIA VARIABLE Y LA ESTRUCTURA RESONANTE, INCORPORANDO LA CITADA LINEA DE TRANSMISION UN ACOPLADOR BIDIRECCIONAL QUE GENERE UNA SEÑAL DE ACOPLADOR DIRECCIONAL PROPORCIONAL A LA SEÑAL REFLEJADA DE LA CITADA ESTRUCTURA RESONANTE, ESTANDO ACONDICIONADA DICHA SEÑAL DE ACOPLADOR DIRECCIONAL POR UN PROCESADOR A FIN DE PROPORCIONAR UNA SEÑAL DE REALIMENTACION A LA ENTRADA DEL OSCILADOR DE FRECUENCIA VARIABLE, DE MANERA QUE SE CONSIGA QUE LA FRECUENCIA MEDIA DE DICHA SEÑAL DE EXCITACION SIGA CONTINUAMENTE LA FRECUENCIA RESONANTE VARIABLE DE DICHA ESTRUCTURA RESONANTE. EL SEGUIMIENTO DE DICHA FRECUENCIA RESONANTE VARIABLE INCLUYE TIPICAMENTE AL MENOS DOS FUNCIONES: UNA PRIMERA FUNCION DE BUSQUEDA PARA INVESTIGAR INICIALMENTE LA POSIBLE GAMA DE FRECUENCIAS RESONANTES DE DICHA ESTRUCTURA RESONANTE Y, UNA VEZ ESTABLECIDA LA RESONANCIA DE DICHA ESTRUCTURA RESONANTE, UNA SEGUNDA FUNCION DE SEGUIMIENTO PARA SEGUIR DICHA FRECUENCIA RESONANTE VARIABLE, A MEDIDA QUE VARIA EN FUNCION DEL TIEMPO.
