Abstract

Red conformadora de haces para agrupaciones de antenas basada en matrices ópticas de elementos desfasadores/retardadores fijos. Una red conformadora de haces basada en matrices de Butler ópticas sobre la que se aplican una serie de modificaciones destinadas a aumentar el número de posibles haces generados por la matriz, aprovechar de un modo inmediato y simple la capacidad multihaz intrínseca a la misma, dotar a la arquitectura de la capacidad de ajustar la posición angular de los posibles haces, simplificar de manera notable el diseño final de la red conformadora y dotar a la red de la capacidad de generar simultáneamente determinados frentes de fase y sus opuestos. La invención propuesta es asimismo aplicable a otras estructuras de matriz óptica de elementos desfasadores/retardadores fijos (como las matrices de Blass o Rotman) y, en general, a otras arquitecturas de conformación heterodina.
