A Fast Ray-tracing-based Algorithm for Very Low Frequency Radio Propagation

In order to get the radio propagation path through the atmosphere, a common ray tracing model is introduced and the acquisition methods of relevant parameters are given according to the actual situation in China. This calculation method can quickly simulate the electromagnetic wave propagation paths. The algorithm has the characteristics of high practicability and accuracy for calculating ray path. In this paper, a case has been studied for illustrating the advantages of using the ray tracing algorithm mentioned above.
