Abstract

Se activa un ataque en un amplificador receptor de un interrogador siempre que una senal de entrada amplificada excede un valor de voltaje umbral de ataque Vatt, y el amplificador receptor por lo menos durante un periodo de espera, cuya longitud preferiblemente es igual al doble de la longitud del intervalo de tiempo mas prolongado entre impulsos adyacentes en un paquete de onda de datos de transpondedor, despues del final del ataque no responde en el sentido del establecimiento de ganancia. No obstante, el amplificador responde con una disminucion activada despues del lapso de periodo de espera, el cual se inicia cuando el valor de la senal amplificada instantanea para la ultima vez despues del final del ataque excede un nivel de voltaje umbral de espera Vw. La velocidad de extincion es del mismo orden de magnitud que la velocidad de ataque. El metodo mejorado para establecer automaticamente la ganancia vuelve posible que el receptor interrogador dentro de un sistema de identificacion sin contacto practicamente no cambie las caracteristicas esenciales de la senal de entrada.
