Summary:
Rain attenuation is powerful to interrupt the service availability of satellite communication especially in higher frequency above 20 GHz. Several countermeasure techniques has been propose to maintain satellite link service. In this paper, we evaluate the performance of boost beam method as one of satellite power control method by using rain radar data produced by Japan Meteorological Agency. We use boost power constant at 20 mm/h approximately equivalent to 10 dB of power margin at 22 GHz link. We divide boost beam size to 50,100,150 and 200 km and 1 to 4 of boost beam number. We analyze the cumulative distribution of rainfall rate intensity in case of no boost and each boost case. We confirm this method can be reduce rain attenuation effect in many peak areas.
