Abstract
Un receptor para un sistema de guía de radio, del tipo en el que se transmite un solo haz colimado en frecuencia que barre el sector y, bien se realiza la transmisión por todo el sector, o bien existe una generación de pre-detector en el receptor de una señal de referencia, de una frecuencia derivada de la frecuencia del haz. Dicho receptor incluye elementos para procesar la señal del post -detector, que comprenden una puerta de tiempo para inhibir aquellas partes de la señal del haz principal que corresponden a los ángulos fuera del sector y acoplados a la salida de dicha puerta de tiempo, existe un filtro para reducir de una manera significativa la contribución al espectro total de los lóbulos laterales residuales de cualquier señal del haz fuera del sector.
