【摘要】 激光在海水中传播的后向散射一直是影响水下激光探测的一个重要因素,强烈的后向散射使得目标回波信号被淹没。本文首先用蒙特卡罗分析法对激光束在海水中的传输进行建模,计算统计激光在传输过程中的后向散射光子数,然后从激光传输方程出发,计算回波信号和后向散射信号的强度比,模拟激光探测中实际的回波信号的后向散射信号。
【Abstract】 Backscattering has been one of the most important factors which affecting the laser detection in ocean water.The target echo signal will be lost if the backscattering is strong enough.This paper analysis the transmission properties of laser in the seawater using the Monte Carlo.First we built the model of the laser transmission in the seawater.And then the ratio of the echo signal and the backscattering signal was calculated by the laser transmission equation.All did in this paper was to simulation the real signal which the system received in the seawater.
