A multi-dimensional beamforming device that performs consecutive one- dimensional operations. For example, beamsteering for a two-dimensional array can include a projection of a beam onto each of the respective axes of the array. In such a device, a first beamforming processing element is used to form multiple beams for each array output along a given row. In a preferred embodiment, sequential output vectors from the first processing element are then applied to a transposing or corner turning memory and the data are reformatted such that all elements on a given column of the array are applied to a second beam forming processing element.

L'invention concerne un dispositif de formation de faisceaux multidimensionnel qui effectue des opérations unidimensionnelles consécutives. Par exemple, le pointage de faisceaux associé à une matrice bidimensionnelle peut comprendre une projection d'un faisceau sur chacun des axes respectifs de la matrice. Dans un tel dispositif, on utilise un premier élément de traitement formant des faisceaux pour former plusieurs faisceaux pour chaque sortie de matrice, le long d'une rangée donnée. Dans un mode de réalisation préféré, on applique les vecteurs de sortie séquentiels provenant du premier élément de traitement, à une mémoire de transposition ou de rotation et on reformate les données, de sorte que tous les éléments d'une colonne donnée de la matrice sont appliqués à un second élément de traitement formant des faisceaux.
