Title (EN) A METHOD AND A UNIT FOR BEAM CONTROL OF AN ARRAY ANTENNA
(FR) PROCEDE ET UNITE DESTINES A CONTROLER LE FAISCEAU D'UNE ANTENNE RESEAU
Abstract: front page image
(EN)A method of producing a digital beamformer signal by a number of antenna modules that are alike and by providing a system that implements the method. This is accomplished by introducing signal processing on each antenna module and by creating an asynchronous serial adding chain through the antenna modules to at least in part calculate the digital beamformer signal. Advantageous embodiments according to the invention perform time and space signal processing multiplexing to calculate additional digital beamformer signals.
(FR)Procédé pour produire un signal formateur de faisceau numérique au moyen d'un certain nombre de modules d'antenne similaires et d'un système qui met en oeuvre ce procédé. Selon l'invention, on introduit le traitement de signaux dans chaque module d'antenne et on crée une chaîne d'addition sérielle asynchrone en passant par les modules d'antennes pour calculer au moins en partie le signal formateur de faisceau numérique. Dans des modes réalisation avantageux, on effectue le multiplexage du traitement des signaux temporel et spatial afin de pouvoir calculer les signaux formateurs de faisceaux numériques supplémentaires.
