CO OZNACZA SŁOWO PHASED ARRAY
Rozszerzona tablica
W teorii anteny, stopniowana tablica to tablica anten, w której względne fazy odpowiednich sygnałów podających anteny są zmieniane w taki sposób, że skuteczny wzór promieniowania tablicy wzmacnia się w pożądanym kierunku i tłumi w niepożądanych kierunkach. Tablica anteny to grupa wielu aktywnych anten połączonych ze wspólnym źródłem lub obciążeniem w celu uzyskania wzoru promieniowania dyrektywy. Zwykle relacje przestrzenne poszczególnych anten przyczyniają się również do kierowania tablicą anten. Użycie terminu "aktywne anteny" ma na celu opisanie elementów, których moc wyjściowa energii jest modyfikowana ze względu na obecność źródła energii w elemencie lub elemencie, w którym energia wyjściowa ze źródła energii jest sterowana przez wejście sygnału. Jednym z powszechnych zastosowań jest standardowa multibandowa antena telewizyjna, która łączy wiele elementów.
Definicja słowa phased array w słowniku
Definicja macierzy fazowanej w słowniku to tablica anten radiowych połączonych ze sobą w jedną antenę. Wytwarzana wiązka może być sterowana przez niebo poprzez regulację faz sygnałów. Brak ruchomych części umożliwia bardzo szybkie sterowanie wiązkami, dzięki czemu jest przydatny w radarach.
