补充资料:长波通信
      波长为10000~1000米(频率为30~300千赫)的无线电通信。长波以地波及天波的形式传播。在一定范围内,长波通信以地波传播为主,当通信距离大于地波的最大传播距离时,则靠天波来传播信号。长波通信的优点是:通信距离远,能透入岩层、海水一定的深度,受太阳耀斑和核爆炸的影响小,通信比较稳定可靠。其缺点是:发信设备及天线系统庞大,造价高;通频带窄,不适于多路和快速通信;易受天电干扰。长波通信主要用于对潜艇通信、远洋通信、地下通信及导航等。其通信方式主要是人工报和低速印字报,频段高端也可通单边带话。
  
  长波通信的历史,可追溯到1901年意大利物理学家G.马可尼进行的跨越大西洋的越洋通信试验。1925年后,由于发现短波能靠电离层反射进行远距离传播,才逐步用短波通信取代一般的长波通信。第二次世界大战中,因对潜艇通信的需要,而又重视发展长波通信。随着导弹、核武器的发展,导致越来越多的军事设施转入地下,长波地下通信将是保障地下指挥所和坑道间应急通信的重要手段。
