PRECIS DE LA DIVULGATION L'invention a pour objet un dispositif de calcul d'une transformée de Fourier discrète, glissante et non- récursive, notamment applicable au traitement du signal d'un radar à compression d'impulsion. Il comporte N é- tages identiques et parallèles (Ek) recevant chacun des é- chantillons du signal d'entrée (em+N) . Chacun des étages comporte deux opérateurs de rotation complexe, deux additionneurs-soustracteurs et deux circuits de retard et fournit un signal X?k+1 obtenu à partir des équations suivantes: X? = Image ; Image = Image ; et X'm= Image .
