CHE SIGNIFICA PHASED ARRAY IN INGLESE
Un array fasi
Nella teoria dell'antenna, un array a fasi è una serie di antenne in cui le fasi relative dei rispettivi segnali che alimentano le antenne vengono variate in modo tale che il modello di radiazione effettivo dell'array sia rinforzato in una direzione desiderata e soppressa in direzioni indesiderate. Un array di antenne è un gruppo di più antenne attive accoppiate ad una sorgente o un carico comuni per produrre un modello di radiazione di direttiva. Di solito, il rapporto spaziale delle singole antenne contribuisce anche alla direttività dell'antenna. L'uso del termine "antenne attive" è inteso a descrivere elementi la cui produzione di energia è modificata a causa della presenza di una fonte di energia nell'elemento o in un elemento in cui l'uscita di energia proveniente da una fonte di energia viene controllata dall'ingresso del segnale. Un'applicazione comune di questo è con un'antenna standard televisiva a banda larga, che ha più elementi accoppiati insieme.
definizione di phased array nel dizionario inglese
La definizione di phased array nel dizionario è una serie di antenne radio collegate tra loro per formare un'unica antenna. Il raggio prodotto può essere guidato attraverso il cielo regolando le fasi dei segnali. L'assenza di parti mobili consente di sterzare i fasci molto rapidamente, rendendolo utile nel radar.
