QUE SIGNIFIE PHASED ARRAY EN ANGLAIS
Arrondi progressif
Dans la théorie de l'antenne, un réseau en phase est un réseau d'antennes dans lequel les phases relatives des signaux respectifs alimentant les antennes sont modifiées de telle sorte que le motif de rayonnement efficace du réseau est renforcé dans une direction souhaitée et supprimé dans des directions indésirables. Un réseau d'antennes est un groupe d'antennes actives multiples couplées à une source commune ou une charge pour produire un diagramme de rayonnement de directive. Habituellement, la relation spatiale des antennes individuelles contribue également à la directivité du réseau d'antennes. L'utilisation du terme "antennes actives" est destinée à décrire des éléments dont la sortie d'énergie est modifiée en raison de la présence d'une source d'énergie dans l'élément ou un élément dans lequel la sortie d'énergie d'une source d'énergie est contrôlée par l'entrée du signal. Une application commune de ceci est avec une antenne de télévision multibande standard, qui a plusieurs éléments couplés.
définition de phased array dans le dictionnaire anglais
La définition du réseau en phase dans le dictionnaire est un réseau d'antennes radio connectées ensemble pour former une seule antenne. Le faisceau produit peut être dirigé à travers le ciel en ajustant les phases des signaux. L'absence de pièces mobiles permet de diriger les faisceaux très rapidement, ce qui le rend utile dans le radar.
