Abstract
(EN)
A process for cooperative aerial inter-antenna beamforming for communication between (a) multiple moving platforms, each platform having an aerial antenna mounted thereon, such that one or more aerial antennas have variable positions and orientations over time, and (b) first and second antennas connected to user equipment having a lower altitude than the aerial antennas; the process involving transmitting data relating to the positions and orientations of the aerial antennas to a processing system, the processing system calculating and transmitting beamforming instructions to the aerial antennas, the aerial antennas thereby transmitting or receiving respective first component signals for the first user antenna, and transmitting or receiving respective second component signals for the second user antenna, the first component signals each having essentially the same information content but differing in their phase and usually amplitude, the second component signals each having essentially the same information content but differing in their phase and usually amplitude, so as to form a first cooperative beam from the cooperative sum of the signals between the aerial antennas and the first user antenna, and a second cooperative beam from the cooperative sum of the signals between the aerial antennas and the second user antenna.

Procédé de formation de faisceau coopératif entre antennes aériennes pour la communication entre (a) de multiples plates-formes mobiles, chaque plate-forme ayant une antenne aérienne montée sur celle-ci, de telle sorte qu'une ou plusieurs antennes aériennes aient des positions et des orientations variables dans le temps, et (b) une première et une seconde antenne reliée à un équipement utilisateur ayant une altitude inférieure à celle des antennes aériennes; le procédé comprend la transmission de données relatives aux positions et orientations des antennes aériennes à un système de traitement, le système de traitement calculant et transmettant des instructions de formation de faisceau aux antennes aériennes, les antennes aériennes transmettant ou recevant ainsi des premiers signaux de composants respectifs pour la première antenne d'utilisateur, et transmettant ou recevant des seconds signaux de composants respectifs pour la seconde antenne d'utilisateur, les premiers signaux de composants ayant chacun essentiellement le même contenu d'information mais différant dans leur phase et habituellement leur amplitude, et les seconds signaux de composants ayant chacun essentiellement le même contenu d'information mais différant dans leur phase et habituellement leur amplitude, de manière à former un premier faisceau coopératif à partir de la somme coopérative des signaux entre les antennes aériennes et la première antenne d'utilisateur, et un second faisceau coopératif à partir de la somme coopérative des signaux entre les antennes aériennes et la seconde antenne d'utilisateur.
