Prediction of ionospheric fading for long distance emergency communication

研究成果: Conference contribution

抄録

High Frequency is the suitable frequency for emergency communication. The existence of ionosphere that layered over the earth enables us to communicate on long distance, but at the same time, the ionosphere is one of the causes of radio wave fading in High Frequency communication, which produces deterioration of communication quality. It is known that the fading occurs by the spatial moving of electron density irregularity structure in the ionosphere. This paper focuses on the daily change of electron density in the ionosphere to investigate High Frequency band long distance propagation characteristics through the ionosphere. In order to evaluate it, we made a simulator using ray-tracing. From the simulation result, we succeeded in demonstrating the existence of fading mainly due to changes in electron density which has not been conventionally discussed. This work provides an unprecedented reference for better understanding of the fading regard to High Frequency band.
