翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Television guidance ： ウィキペディア英語版 Television guidance Television guidance (TGM) is a type of missile guidance system using a television camera in the missile or glide bomb that sends its signal back to the launch platform. There, a weapons officer or bomb aimer watches the image on a television screen and sends corrections to the missile, typically over a radio control link. Television guidance is not a ''seeker'' because it is not automated, although semi-automated systems with autopilots to smooth out the motion are known. They should not be confused with contrast seekers, which also use a television camera but are true automated seeker systems. The concept was first explored by the Germans during World War II as an anti-shipping weapon that would allow attacks on ships while the launch aircraft remained safely out of range of the target's anti-aircraft guns. The best developed was the Henschel Hs 293. The US also experimented with similar weapons during the war, notably the GB-4 and TRD-1. Only small numbers were used experimentally and with poor results. One of the first TV guided weapons to see widespread service was the Anglo-French Martel missile, which came in radar-seeking and TV guided versions. The US AGM-62 Walleye is a similar system attached to an unpowered bomb, the Soviet Kh-29 is similar. Television guidance was never widely used, as the introduction of laser guided bombs and GPS weapons have generally replaced them. However, they remain useful when certain approaches or additional accuracy are needed. One famous use was the attack on the Sea Island oil platform during the Gulf War, which required pinpoint accuracy. ==History== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Television guidance」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
