Abstract
UN SISTEMA RADAR (20) TIENE UNA FUENTE DE CODIGO CAOTICO (22) CON UNA SALIDA DE CODIGO CAOTICO (23), QUE GENERA UN CODIGO CAOTICO ACORDE A UNA ECUACION DE DIFERENCIA CAOTICA. EL SISTEMA RADAR (20) ADEMAS INCLUYE UN TRANSMISOR (24) CON UNA FUENTE DE SEÑAL PORTADORA (28) DE UNA SEÑAL PORTADORA (29), Y UN CODIFICADOR (30) QUE TIENE COMO UNA PRIMERA ENTRADA LA SEÑAL PORTADORA (29) DE LA FUENTE DE SEÑAL PORTADORA (28) Y COMO UNA SEGUNDA ENTRADA LA SALIDA DE CODIGO CAOTICO (23) DE LA FUENTE DE CODIGO CAOTICO (22), Y COMO UNA SALIDA UNA SEÑAL DE RADAR TRANSMITIDA (36) QUE TIENE LA SALIDA DE CODIGO CAOTICO (23) CODIFICADA EN LA SEÑAL PORTADORA (29). UN RECEPTOR DEL SISTEMA DE RADAR (26) INCLUYE UN CORRELADOR (46) QUE TIENE COMO UNA PRIMERA ENTRADA LA SALIDA DE CODIGO CAOTICO (23) DE LA FUENTE DE CODIGO CAOTICO (22) Y COMO UNA SEGUNDA ENTRADA UNA SEÑAL DE RADAR RECIBIDA (44), Y COMO UNA SALIDA UNA INDICACION DE LA CORRELACION DE LA PRIMERA Y SEGUNDA ENTRADAS. LA CORRELACION ES USADA PARA DETERMINARLA DISTANCIA, VELOCIDAD, U OTRAS CARACTERISTICAS DE UN OBJETO QUE HA REFLEJADO LA SEÑAL DE RADAR.
