摘要: 通过建立光传导的Monte Carlo模型和唯像理论模型,对激光在海水中的传输进行了模拟,把最大测深随海水衰减系数的变化和光斑大小与测深的关系进行了深入研究,得出了唯像模型适用于远海岸的清洁水,而Monte Carlo模型在近海岸的浑水中比较符合,并通过光斑分析了激光水下能量的分配,分析了正在研制的机载激光雷达测深系统,论证了系统的可行性。

Abstract: The simulations were performed to study the Airborne Lidar Bathymetry System by application of Monte Carlo model and Phenomenological model to describe the transmission of Gauss laser beam in ocean water. Research on the relation between seawater dielectric attenuation coefficient and maximum detecting depth was conducted. The change of facular size with detecting depth was explored. Simulation results show that two models are appropriate for different instance. Part of the Airborne Lidar's parameters was analyzed by the two models. According to simulation results, the Airborne Lidar scheme is demonstrated to be feasible.

Key words: Monte Carlo model, phenomenological model, gauss laser beam, airborne Lidar
