摘要：
Propagation impairments produced by the troposphere have great impact in ka-band (or higher) satellite communication system, and the rain attenuation is the leading factor that affects the communication capability and the quality of transmission. So, it is necessary for us to calculate the rain attenuation accurately, and then take some measures to reduce the effect by rain. This paper computes rain attenuation at any location in China using Chinese-modified model based on ITU-R model combined with frequency extrapolation. In addition, we introduce a novel model which improved the compute efficiency and reduce CPU load, the calculated results show that this model is effective and exact.
