水下潜艇如何与飞机直接通信?MIT实现"海天交流"

网易科技 2018-08-23

  8月23日消息,据国外媒体报道,长期以来水下潜艇无法与飞机直接进行通信。本周二,麻省理工学院媒介实验室(MIT Media Lab)发布了一项实现水下到空中通信的新技术,这堪称一项前所未有的壮举。

  由于彼此的通信介质不匹配,因此长期以来水下潜艇无法与飞机进行直接通信。潜艇使用声纳,而飞机使用无线电信号、蜂窝系统或GPS。声纳信号无法穿透水面,而无线电信号在水下的传播效果不好。

  但麻省理工学院有了解决方案。

  研究人员利用水下发射器向游泳池表面发送声纳信号,引起微小的震动。这种振动信号由敏感雷达所接收,随后雷达将以振动方式传输的1和0进行解码。

  该研究论文合著者、媒介实验室助理教授法德尔·阿迪布(Fadel Adib)表示,这种通信系统是一个“里程碑”。

  该系统被称为“平移声学-射频通信”(TARF)。麻省理工学院表示,它可以用来寻找水下失踪的飞机,允许军用潜艇在无需浮出水面暴露位置的情况下与飞机进行通信,还可以让水下无人机持续性监测海洋生物,而无需浮出水面传输数据。(晗冰)
