We propose an algorithm and the results of a numerical study of random realizations and statistics of a pulsed coherent lidar return that allow for refractive turbulence. We show that, under conditions of refractive turbulence, the relative variance of the lidar return power can exceed unity by a factor of as much as 1.5. Clear manifestations of the turbulent effect of backscattering amplification have been revealed from simulations of space-based lidar sensing of the atmosphere with coherent lidar. Under conditions of strong optical turbulence in the atmospheric boundary layer, as a result of the backscattering amplification effect, the mean lidar return power can exceed the return power in the absence of turbulence by a factor of 3.
我们提出了一种算法以及对考虑了折射湍流的脉冲相干激光雷达回波的随机实现和统计进行数值研究的结果。我们表明，在折射湍流条件下，激光雷达回波功率的相对方差可能比单位值高出多达1.5倍。通过对基于空间的相干激光雷达大气传感进行模拟，已经揭示了后向散射放大湍流效应的明显表现。在大气边界层强光学湍流条件下，由于后向散射放大效应，激光雷达回波平均功率可能比无湍流时的回波功率高出3倍。
