METHOD FOR PROPAGATION CHANNEL MODELINGS OF EARTH'S ATMOSPHERE

摘要

According to the present invention, the propagation characteristics of the troposphere and the stratosphere are modeled using ray tracing, and the propagation characteristics of the ionosphere are modeled using the finite difference time domain method by inputting data of the electric field passing through the troposphere and the stratosphere. As a global atmospheric propagation channel modeling method comprising a, according to the present invention, it is possible to more accurately derive the signal position on the ground by considering the propagation environment by dividing the atmosphere.
