摘　　要：从分析海水、大气对光的吸收和散射出发,对海水、海水/大气界面及大气等各种因素对激光传输的影响作了较全面的描述,并由此推出蓝绿激光通过上行传输信道后接收信号的能量方程。在信号能量传递的计算中,根据Bucher方程得到了时间扩展后的脉冲波形的近似表达式。计算机仿真得到了一些主要参数的实验模拟结果。Describes passage characteristic of laser transmission in the optical channel from analyzing absorption and scattering of ocean water and atmosphere. A complete description of the influences of various factors such as sea water, water/air interface and the cloud on the signal attenuation is made. After the bluegreen laser transfers the uplink propagation channel, The energy equation of the received signal can be got. In the signal energy transmission calculation, an approximate expression for the timeexpanded pulse wave is obtained from Bucher equation.The experiment simulation result has been got under some main parameters by the simulation of the computer.
