本文以球形粒子的mie散射理论、 stokes矢量法以及mueller矩阵来研究海水的散射特性和散射中的退偏振度变化;通过montecarlo方法模拟蓝绿激光在海水传输过程中的散射现象以及散射中的退偏度变化与海水深度的关系,发现随着海水深度的增加,散射后的光斑半径、退偏振度将逐渐增大。最后通过光学工程软件( lighttools )对海水中的散射进行仿真实验,研究散射与海水中粒子密度、粒子大小和相对折射率的关系。实验结果表明,随着粒子半径、粒子密度和相对折射率的增加,散射的强度将显著增加。 - Be based upon the studies of sea optical scatter channel by use of monte carlo simulation , the channel is described as a multipath routeway in this paper . the effect on the communications performance , created by the frequency selectivity decline caused by the multipath routeway , is worked over . the correlation bandwith of sea optical scatter channel is analyzed and quantified through the simulation on the computer
