Abstract

La présente invention se rapporte à un dispositif de traitement numérique pour une antenne réseau. Selon l'invention, les signaux reçus par les dix éléments d'antenne 1 à 10 sont échantillonnés puis appliqués à une unité de réarrangement RO. Les échantillons sont réarrangés selon un algorithme p = g**i modulo N où p et g sont des échantillons des séquences initiale et réarrangée respectivement et N est le nombre d'échantillons. Une ligne à retard est utilisée dans l'unité RO et également dans le filtre transversal TF. L'invention s'applique dans le domaine radar.The present invention relates to a digital processing device for an array antenna. According to the invention, the signals received by the ten antenna elements 1 to 10 are sampled and then applied to a rearrangement unit RO. The samples are rearranged according to an algorithm p = g ** i modulo N where p and g are samples of the initial and rearranged sequences respectively and N is the number of samples. A delay line is used in the RO unit and also in the TF transverse filter. The invention applies to the radar field.
