CHE SIGNIFICA DIRECTION FINDING IN INGLESE
Individuazione della direzione
La ricerca della direzione o la ricerca della direzione radio, si riferisce alla misura della direzione da cui è stato trasmesso un segnale ricevuto. Questo può fare riferimento a radio o altre forme di comunicazione wireless. Combinando le informazioni di direzione da due o più ricevitori opportunamente distanziati, la sorgente di una trasmissione può essere collocata nello spazio tramite triangolazione. La ricerca della direzione radio viene utilizzata nella navigazione di navi e aeromobili, per individuare i trasmettitori di emergenza per la ricerca e il salvataggio, per il monitoraggio della fauna selvatica e per individuare trasmettitori illegali o interferenti. I sistemi RDF possono essere utilizzati con qualsiasi sorgente radio, anche se le dimensioni delle antenne riceventi sono una funzione della lunghezza d'onda del segnale: lunghezze d'onda molto lunghe richiedono antenne molto grandi e sono generalmente utilizzate solo su sistemi a terra. Queste lunghezze d'onda sono tuttavia molto utili per la navigazione marina marina, in quanto possono percorrere lunghe distanze "sull'orizzonte", utile per le navi quando la linea di visibilità può essere solo qualche decina di chilometri. Per l'uso aereo, dove l'orizzonte può estendersi a centinaia di chilometri, possono essere impiegate frequenze superiori, consentendo l'utilizzo di antenne molto più piccole.
definizione di direction finding nel dizionario inglese
