Ka-band satellite beacon attenuation and rain rate measurements in Singapore - comparison with ITU-R models

The preliminary results of the analyses performed suggest that the rainfall rate with 1 min integration time has a good agreement with the rainfall rate predicted from ITU-R model, regardless of yearly or worst month statistics. However ITU-R P.618-9 tends to underestimate the rain attenuation for t...

Description
Summary:The preliminary results of the analyses performed suggest that the rainfall rate with 1 min integration time has a good agreement with the rainfall rate predicted from ITU-R model, regardless of yearly or worst month statistics. However ITU-R P.618-9 tends to underestimate the rain attenuation for the earth-space link in tropical areas like Singapore. A modified model of rain attenuation prediction is proposed. Beacon data are still collected and the effect of raindrop on antenna should be studied further.
