Abstract
L'invention concerne un dispositif de formation de faisceau d'énergie de rayonnement reçu ou émis par un réseau d'éléments rayonnants. Lorsqu'un front d'onde progresse le long du réseau, des échantillons des signaux reçus par des transducteurs du réseau sont sélectionnés, et les échantillons sélectionnés sont additionnés en une série de sommations partielles jusqu'à ce qu'un échantillon complet du faisceau soit obtenu. La série de sommations partielles est déclenchée successivement pendant chaque intervalle d'échantillonnage de sortie. L'invention s'applique notamment à des dispositifs sonar.
