Keyword大气光学 湍流间歇性 She模型 扩展和漂移 激光测距 回波光子
Abstract

基于大气湍流中的光传输理论,并利用与实际大气湍流更为接近的间歇性湍流的She模型,得到了适用于Kolmogorov大气湍流、间歇性大气湍流的光束长期项扩展和短期项漂移的近似解析式;结合激光测距方程,利用Matlab软件计算了低轨卫星、高轨卫星和月球的测距回波光子数,分析了大气湍流的间歇性对激光测距回波光子数的影响。结果表明,大气湍流的间歇性越大,测距回波光子数越多;回波光子数在间歇性大气湍流与无湍流情况下的比值约为1/20。

Other Abstract

Based on the optical transmission theory in atmospheric turbulence, approximate analytical expressions of light beam long-term extension and short-term drift which are suitable for Kolmogorov atmospheric turbulence are obtained when we use the She model of in termittent turbulence, and the She model is close to the actual atmospheric turbulence. Combining with the laser ranging equation, the numbers of ranging return photon from low orbit satellite, high orbit satellite and moon are calculated by Matlab software. The influence of atmospheric turbulence intermittency on return photon number in laser ranging is analyzed. Results show that the larger the turbulence intermittency is , the larger the ranging return photon number is. The ratio of return photon number in the case of with intermittent atmospheric turbulence to turbulence is about 1/20.
