Abstract
LA INVENCION SE REFIERE A UN RECEPTOR UKW CON ANTENAS MULTIPLES, DONDE LA SEÑAL HF RECIBIDA DE CADA ANTENA ES MEZCLADA CON UNA SEÑAL GENERADA EN EL RECEPTOR DE UN PRIMER OSCILADOR EN UNA ETAPA DE MEZCLA ESTABLECIDA EN UNA DE LAS CORRESPONDIENTES ANTENAS Y POR CONSIGUIENTE LAS SEÑALES DE MEZCLAS ORIGINADAS SE ADICIONAN CON LA SITUACION DE FASE CONTROLABLE PARA LA OBTENCION DE UNA SEÑAL SUMA. SE ALMACENAN LAS FRECUENCIAS ALTERNATIVAS SUMINISTRADAS DE UN DEMODULADOR RDS. SE UTILIZA UNA DE LAS ETAPAS DE MEZCLA PARA LA ACTUALIZACION DE LAS FRECUENCIAS ALMACENADAS CON EL VALOR DE NIVEL DE CALIDAD RECEPTORA PERTENECIENTE EN EL PUNTO DE TIEMPO CORTO DETERMINADO DE ANTEMANO. EN EL CASO DE QUE EL NIVEL DE CALIDAD DE RECEPCION DADA QUEDE POR DEBAJO DE UN VALOR EL RECEPTOR SE CONECTA SEGUN UNA FRECUENCIA ALTERNATIVA ALMACENADA Y CONOCIDA COMO CALIDAD DE RECEPCION APROPIADA.
