Abstract
CORRELACIONADOR DIGITAL DE ALCANCE Y METODO PARA PROPORCIONAR UNA CORRELACION DIGITAL DE ALCANCE; SE PROPORCIONA UN ESQUEMA DE CORRELACION QUE PUEDE SER MECANIZADO Y PRODUCIDO REPETIDAMENTE CON UNA MINIMA NECESIDAD DE DESPLAZAMIENTOS Y CON SENSIBILIDAD DE ALIMENTACION DE CORRIENTE REDUCIDA. EL CORRELACIONADOR DIGITAL (10) DEL PRESENTE INVENTO INLCUYE UN CONVERTIDRO (12) DE ANALOGICO A DIGITAL PARA CONVERTIR UNA SEÑALA ANALOGICA DE ENTRADA EN UNA SEÑAL DIGITAL PARA PROPORCIONAR UNA PLURALIDAD DE PALABRAS DIGITALES, UNA DE LAS CUALES CORRESPONDE A CADA PUERTA DE ALCANCE. HAY PREVISTO UN ACUMULADOR (22) PARA SUMAR LOS BITIOS DE CADA PALABRA DIGITAL PARA PROPORCIONAR UNA SUMA ACUMULADA PARA CADA PUERTA DE ALCANCE. LAS SUMAS DIGITALES SON COMPARADAS EN UN PROCESADOR (26) PARA IDENTIFICAR LA PUERTA DE ALCANCE DEL OBJETIVO. SE PERMITE LA INCORPORACION DE UN CODIGO DE CORRELACION. APLICACION PARTICULAR EN AERONAUTICA.
