| 摘 要： | 研究了计算海面激光反射的几何光学方法。首先根据JONSWAP非稳态海谱模型数值模拟出二维随机粗糙海面，再采用几何光学方法对入射激光光束在海面上的反射光进行建模，最后计算出海面激光光斑反射光强的空间分布。编制了相关的计算机程序，分析了在不同入射角度和不同风速下的激光光束反射特性。计算结果表明该方法对研究二维随机粗糙海表面激光反射特性有一定参考价值。 |

| Abstract: | The geometrical optical method to study the laser reflection performance from the random and rough sea surface is discussed in this paper. First, the two-dimensional random and rough sea surface based on JONSWAP spectrum is simulated. After that, a model of reflected laser beam from rough sea surface with geometrical optical method is established, and the reflected laser intensity space distribution from sea surface is available. A program is developed to analyze reflected laser beam at different incident angle and sea surface at different wind speed. The result is useful for study on laser reflection from the two-dimension stochastic and rough sea surface. |
| Keywords: | laser reflection geometrical optics rough sea surface reflection performance |
