【摘要】 针对大气-海水界面对光脉冲传输的影响,利用蒙特卡罗(Monte Carlo)方法模拟三维海浪,从不同风级下的大气-海水界面模型得出有效波高H1/3的俯仰角期望值以及对应的反射率,并通过模拟光脉冲传输过程得出水下接收面光斑分布的统计数据。模拟结果表明:有效波高H1/3的俯仰角大约在0.5910rad(即34°左右)时,对激光脉冲开始产生明显的影响;当风级增大到8级时,激光脉冲传输发生了剧烈的变化。更多还原

【Abstract】 With consideration of laser pulse transmission influenced by air-sea surface,the 3D wave has been simulated by using Monte Carlo method.The elevation angle expectation and reflectivity of valid wave height have been achieved from air-sea level model in different wind scale.The statistic data of optical spot distribution in underwater receiving surface has been achieved through simulating laser pulse transmission process.The results show that the severe influence to laser pulse has been made when elevation angle of valid wave height is about 0.5910 rad(around 34°).The radical changes to laser pulse transmission has been taken place when wind class increased to level 8.更多还原
