摘要

研究了微波在无雨的对流层中的传播模式。折射率的大尺度变化是由中尺度气象模式计算出来的。考虑到柯尔莫哥洛夫谱的惯性区建立,从大尺度推导出小尺度变化。在考虑大尺度折射率效应和小尺度多相屏技术的抛物波方程分辨率的情况下,应用发射射线对抛物波方程的传播效应进行了估计。该方法已与地球卫星测量鲁万-拉-纽夫测量的对数振幅闪烁进行了评估。

Scintillation modelling in troposphere using Multiple Phase Screen
Microwaves propagation modelling in clear air troposphere i.e. without rain is investigated. Large scale variations of refractivity are computed from mesoscale meteorological modelling. Small scale variations are deduced from large scale considering that the inertial regime of Kolmogorov spectrum is established. The propagation effects are estimated applying launching ray to take into account large scale refractivity effects and resolution of Parabolic Wave Equation with Multiple Phase Screen technique for small scale. The proposed approach has been evaluated versus earth satellite measurements of log-amplitude scintillation measured at Louvain-la-Neuve.
