鱼雷被用作海战武器,已有一百多年的历史。第二次世界大战末期,人们根据声波能在水中传播的原理,研制成一种能自动发现并跟踪敌舰的鱼雷,叫做“自导鱼雷”。这种鱼雷不是用无线电遥控来操作,而是由它自身的“大脑”——雷体前段的音响自导系统操纵航向和跟踪敌舰的。 Torpedoes have been used as naval weapons for more than a hundred years. At the end of the Second World War, people developed a torpedo that automatically discovers and tracks enemy ships based on the principle that sound waves can propagate in the water, called “self-guided torpedoes.” Instead of operating on radio remote control, the torpedo was operated by its own “brain,” the acoustic self-steering system in the front of the body, to track and track the enemy ships.
