Research and Exploration on Computation and Countermeasures on Cloud, Fog and Rain Attenuation in Ka-band Satellite Communication

摘要

Satellite communication system design engineers are often concerned with the attenuation caused by propagation in rainfall while ignoring the influence on microwave propagation on satellite-earth link in satellite communication on cloudy, foggy or rainy days. This paper comprehensively gives a calculation method in satellite communication attenuation in the Ka-band. The method can be used as reference for researchers engaged in similar work. In this paper, we analyze the effects of cloud, fog and rain attenuation in Ka-band satellite communication. We also suggest real-time dynamic compensation uplink and fixed rain compensation downlink by rate diversity technology. As a result, this method compensates for cloud, fog and rain attenuation and simplifies satellite control.
