摘要
根据光波斜程传输理论以及随高度变化的ITU-R湍流大气结构常数模型,将水平均匀湍流介质情况下成立的修正Rytov方法扩展到斜程传输问题上,建立了激光高斯波束波从弱湍流区到强湍流区斜程路径考虑湍流内尺度和外尺度的闪烁指数统一模型,在大气结构常数为一定值时可退化到水平传输情况。数值计算分析了1.06 μm、1.315 μm、3.8 μm和10.6 μm等典型波长的波束闪烁特性,结果表明波长较短时,内尺度影响较大,且内尺度效应对闪烁的影响要大于外尺度效应,但在强起伏情况下,外尺度的影响也变得较为显著。
Abstract
Based on both the theory of optical wave propagation on the slant path and the altitude-dependent model of the ITU-R turbulence structure constant, the modified Rytov method, which is applicable to the optical wave propagation on the horizontal path, is extended to the propagation on the slant path. The uniform model of scintillation index considering inner- and outer-scales is derived and obtained from weak to strong fluctuation regions with Gaussian beam incidence, and can degenerate to the result of the zone outer-scale with atmospheric structure constant. The beam scintillation index of the typical wave band with 1.06 μm,1.315 μm, 3.8 μm and 10.6 μm is analyzed. The numerical conclusions indicate the smaller wavelength, the stronger inner-scale and the inner-scale has a stronger impact on scintillation than outer-scale. But in strong fluctuation, the outer-scale effect is prominence.
