CO OZNACZA SŁOWO RADAR
Radar
Radar to system wykrywania obiektów wykorzystujący fale radiowe do określania zakresu, wysokości, kierunku lub prędkości obiektów. Może być używany do wykrywania samolotów, statków, statków kosmicznych, pocisków kierowanych, pojazdów mechanicznych, formacji pogody i terenu. Radar lub antena transmitują impulsy fal radiowych lub kuchenek mikrofalowych, które odbijają się od jakiegokolwiek przedmiotu na swojej drodze. Obiekt zwraca niewielką część energii falowej do naczynia lub anteny, która jest zwykle umieszczona w tym samym miejscu, co nadajnik. Radar został potajemnie opracowany przez kilka narodów przed i za II wojną światową. Termin RADAR został stworzony w 1940 roku przez Navy Stanów Zjednoczonych jako skrót od RAdio Detection And Ranging. Określenie radar od tamtego czasu włącza angielski i inne języki jako wspólny rzeczownik, tracąc całą kapitalizację. Nowoczesne zastosowania radaru są bardzo zróżnicowane, w tym kontrola ruchu lotniczego, astronomia radarowa, systemy obrony powietrznej, systemy antywirusowe; morskich radarów w celu zlokalizowania punktów orientacyjnych i innych statków ...
Definicja słowa radar w słowniku
Definicja radaru w słowniku jest metodą wykrywania położenia i prędkości odległego obiektu, takiego jak samolot. Wiązka wiązki impulsów radiowych o bardzo wysokiej częstotliwości jest transmitowana i odbijana przez obiekt z powrotem do nadajnika, przy czym sygnał jest wyświetlane na ekranie radaru. Kierunek odbitej wiązki i czas między transmisją a odbiorem impulsu determinują położenie obiektu Dawna nazwa: radiolokacja. Inną definicją radaru jest sprzęt używany do takiego wykrywania.
