Abstract
We propose a prediction method to calculate the electromagnetic wave propagation between satellite and ground station in atmospheric environments. In order to consider the atmospheric environments, the atmosphere is stratified by elevation, and the effective refractive index of stratified layers calculated. The effective refractive index is calculated from meteorological data measured by rawinsonde. The measured meteorological data are interpolated to obtain the data of the unmeasured regions. The ray path at the boundary of the stratified atmospheric layers is calculated by ray tracing technique. When the ray path is determined through iteration, electromagnetic fields are calculated by geometrical optics. Our method provides the atmospheric attenuation, dispersive effects, and boresight error at the observation point and can be compared with ITU-R P. 676-12 model.
