摘要

本文用蒙特卡罗模拟方法，研究了用于探测水下目标的海洋激光雷达系统中光束的扩散，得到了各种水质条件下不同深度处水下光斑的半径，结果与国外的有关研究结果相吻合；我们还首次计算了水面上目标返回光斑的半径以及其中的亮度分布，并研究了海浪和泡沫对光束扩散的影响，这些结果对于海洋激光雷达系统的设计具有非常重要的意义。

Abstract

This paper has studied the spreading of light beams in airbome oceanic lidar for detecting underwater targets using Monte Carlo simulation method. In various conditions of the ocean

spreading radii of light spots on the various depths under water are obtained

which are coincided with the related results published abroad. For the first time

we have calculated the spreading radii of the light spots just above the water surface that are reflected by the target and the distribution of radiance within them

We have also studied the influence of sea wave and foam on spreading of light beams. These results are very important for the design of the airborne oceanic lidar.
