Abstract

UN SISTEMA DE GUIA DE RADARES DEPENDIENTE DE UNA FASE, CUYO RECEPTOR SEPARA LOS RETORNOS AL CANAL (22) DONDE SE SUMAN LOS RETORNOS (S) Y UN CANAL POSTERIOR (24) DONDE SE DIFERENCIAN LOS RETORNOS (JD). LAS SEÑALES S Y JD SE COMBINAN (26) Y SE FORMAN EN DOS CANALES POSTERIORES COMO S+JD Y S-JD, AMBOS PASAN A TRAVES DE AMPLIFICADORES CONTROLADOS AGC (28, 30) DENTRO DE UN DETECTOR DE ANGULO DE FASE (32) QUE PROPORCIONA EL ANGULO OBJETIVO (BETA) A LA MIRA. SE APLICA UNA SEÑAL DE PRUEBA AL RECEPTOR CON JD = O, EL VALOR DE SALIDA DEL DETECTOR DE ANGULO DE FASE (32) PARA VARIOS VALORES DE LA ATENUACION AGC SE ALMACENA MEDIANTE UN PROCESADOR DIGITAL (34), Y EL PROCESADOR (34) MODIFICA EL VALOR DE LA FASE DEL OBJETIVO MEDIDO CON LOS VALORES ALMACENADOS PARA CORREGIR LOS ERRORES INDUCIDOS AL AMPLIFICADOR AGC.
