基于激光潜艇通信的光信道综述

激光对潜通信系统能够以较快的速率发送信号到一定的深度海水,该通信系统在对潜通信中有着重要作用。通过对激光对潜通信的研究背景、国内外研究现状以及研究方法的分析,以及海水信道光学特性的研究,说明了研究激光对潜通信上行信道的必要性,特别是对海水-空气界面的模拟仿真。并认为以蓝绿激光通信系统为主,甚低频(VLF)和极低频(ELF)系统为辅的通信系统是未来激光对潜通信的主要发展方向。

Overview of Laser-Based Optical Submarine Communication Channel

The laser submarine communication system is able to send a signal through seawater to a great depth and transmit information at a rapid rate. It is important in the communication with a submerged vessel. The current domestic and foreign research on the laser submarine communication is presented. The research on laser transmitting properties in communication channel is proposed. The necessity of the research on the uplink channel of the submarine communication, especially in seawater-air interface＇s simulation, is shown. This study shows that communication system with the blue-green laser communication system as the core technology and the very low frequency （VLF） and extremely low frequency （ELF） system as the peripheral technology is the direction of the future laser submarine communication.
