Comparison of rain attenuation prediction models with Ku-band beacon measurement for satellite communication system

The bulk of beacon signal attenuation or fading is due to clear-air gaseous absorption (oxygen, water vapour) and stronger attenuation in hydrometeor events (rain, snow, clouds). In this paper, the results of the measurements of rain-induced attenuation in the Radio Wave signal propagating at 11.6995 GHz is presented. This paper also gives the comparison of the measurement result with several models, like ITU-R Model, Crane Global Model, SAM Model, Korea Model and others.
