Abstract

UNA ESTACION (1) DE RECEPCION Y EMISION DISPONE DE UN OSCILADOR (3) HF PARA LA GENERACION DE UNA SEÑAL HF PARA TRANSMISION DE INFORMACION A MULTIPLES TRANSPONDERS (2). LOS TRANSPONDERS (2) DISPONEN POR SU PARTE DE EQUIPOS PARA TRANSMISION DE INFORMACION A LA ESTACION (1) DE EMISION Y RECEPCION. PARA ELLO SE HA PREVISTO EL PRODUCTO INTERIOR DE LA SEÑAL F0 PARA LA TRANSMISION DE UN CERO LOGICO Y LA SEÑAL F1 PARA LA TRANSMISION DE UN UNO LOGICO DE TRANSPONDER CON RESPECTO A LA ESTACION (1) DE RECEPCION Y EMISION IGUAL A 0. ESTO TIENE LA VENTAJA DE QUE CON CICLOS DE PREGUNTA REDUCIDOS PUEDEN SER IDENTIFICADOS MULTIPLES TRANSPONDERS (2), QUE SE ENCUENTRAN EN LA ZONA DE REGISTRO DE LA ESTACION (1) DE EMISION Y DE RECEPCION.
