A technique for phase-up of array antennas of regularly spaced lattice orientation, without the use of a near-field or farfield range. The technique uses mutual coupling and/or reflections to provide a signal from one element to its neighbors. This signal provides a reference to allow for elements to be phased with respect to each other. After the first stage of the process is completed, the array is phased-up into, at most, four interleaved lattices. These interleaved lattices are then phased with respect to each other, thus completing the phase-up process.

L'invention est une méthode de mise en phase des systèmes d'antennes à réseaux à espacement régulier sans l'utilisation du champ proche ou du champ lointain. La méthode utilise le couplage mutuel et/ou la réflexion pour transmettre un signal d'un élément à ses voisins. Ce signal sert de référence pour mettre en phase les éléments les uns par rapport aux autres. Quand la première étape du processus est terminée, le système est mis en phase dans quatre réseaux entrelacés au plus. Ces réseaux entrelacés sont ensuite mis en phase les uns par rapport aux autres, ce qui complète le processus de mise en phase.
