蓝绿激光对潜通信光信道的研究

Light Channels of Blue-Green Laser Communication to Submarine

在蓝绿激光对潜通信系统中 ,不同传输信道对通信能力和通信距离都有不同程度的影响 ,根据这个特点 ,分析传输信道特性和背景辐射 ,理论计算与实地实验表明 :系统在 类海区实现 10 0 m以上深度的通信是可能的 ;通信深度与单脉冲能量 Ep 成非线性关系 ,在通信距离不大时通信深度随 Ep 增大而增大 ,当通信深度达某一深度时 ,通信距离不再随 Ep

In the blue green communication system to submarine, there are different influences to communication capability and communication distance in different transmitting channels The transmitting characteristic and background radiation are analyzed The following results are obtained from calculation and field trial In the classⅠsea area,the communication within 100 m depth layer is possible in this system There is a nonlinear relationship between communication depth (Z) and single pause energy (E p).The communication distance increases along with E p increasing when Z is small; and not increase with E p increasing when Z gets to some value.
