| 摘 要： | 介绍了一种新颖的利用激光雷达测量湍流廓线的原理,通过对经过分层大气湍流的光束波面误差的测量,获取各分层大气湍流的相干长度,据此利用一定的算法反演湍流强度廓线.通过大量的实验,验证了通过测量波面误差获得大气折射率结构常数这种方法的可行性.提出了在一定近似条件下利用平面波积分方程的递推算法反演大气折射率结构常数,获得了较为满意的相似度,并且与球面波算法进行了比较,分析了各自的反演效果.

| Abstract: | The principle of lidar system for measuring vertical profile of the atmospheric refractive index turbulence is demonstrated. The turbulence profile retrieval technique is based on the measurement of coherent lengths of different layers. A new method is introduced using the iterative algorithm of the integration equation of plane wave to retrieve the turbulence profiles. The results were compared with that got from spherical wave equation, and their retrieve effects were analyzed. |
