摘　　要：本文利用蒙特卡罗模拟技术，研究了有效衰减系数Γ与飞机高度Ｈ和视场角ＦＯＶ等系统参数以及体积衰减系数ｃ和单次散射率ω０等水质参数的关系，首次得到了系统最小有效衰减系数的近似计算公式，该公式给出了系统参数乘积（Ｈ·ＦＯＶ）足够大时Γ与水质参数ｃ，ω０之间的定量关系，为海洋激光雷达系统的设计提供了有力的依据．This paper have studied the dependence of the effective attenuation coefficient Г on both the parameters of system(height of plane H and field of view FOV) and parameters of sea water quality(volume attenuation coefficent c, single scattering albedo ωo) based on Monte Carlo simulation technology, which leads to an approximate formula of the minimum effective attenuation coefficient for the first time. The formula shows the quantity relationships between the effective attenuation coefficient and the parameters of sea water quality in the condition(H . FOV) is large enough, and provides powerful basis for the design of the lidar system.
