摘要
超声波可以穿透一定厚度的金属传播,而且传输具有方向性好、能量高的特性,而普通的电磁波无法透过金属传播。目前潜艇外部传感器获取的数据必须通过穿舱布设电缆等措施来实现,必须在舱体上开孔,损害了艇体的结构强度,并且存在安全隐患。采用超声波数据传输技术可以设计非穿透性的潜艇数据传输系统,安装方便、布置灵活,不破坏艇体结构。
Ultrasonic waves can transmit through metal,but ordinary electromagnetic wave can not.Its property is directivity and energy.Now,the data con from the outer sensor of submarine must transmit through cable that lay out in the hull.In this way,the hole is drilled in the hulls,which maybe destroy the structural strength of the hull and cause hidden danger.The technology of data transmission for submarine is based on ultrasound waves,which realizes conveniently,and doesn＇t destroy the hull structure.
