The operation of an airborne lidar intended for the detection of fish schools is numerically simulated by the Monte Carlo method. The calculations are performed for schools located at small depths in order to study the regularities in the shaping of the lidar return accurately. Three models of the phase function of scattering of laser radiation in sea water are used. The signals reflected from surface waters that contain a school of fish are determined as a function of the lidar parameters, light scattering and absorption coefficients in the water, stratification of light scattering layers, and fish-school depth. The results obtained can be used for interpreting the signals of the fish-detection lidar.
采用蒙特卡罗方法对用于探测鱼群的机载激光雷达的运行情况进行了数值模拟。为了准确研究激光雷达回波形成的规律，对位于小深度的鱼群进行了计算。使用了三种海水激光辐射散射相函数模型。根据激光雷达参数、水中光散射和吸收系数、光散射层分层情况以及鱼群深度，确定了含有鱼群的表层水反射的信号。所得结果可用于解释鱼群探测激光雷达的信号。
