概要 This paper presents the recent experimental results concerning rain attenuation on radiowave propagation in Ku-band satellite channels at different locations about 100 km far away from each other in K...yushu Island, Japan. We utilize the JCSAT-1B satellite and several VSATs installed at three locations, Oita University at Oita, Kumamoto University at Kumamoto and Kyushu University at Fukuoka, respectively. Rain attenuation is measured using those VSATs at uplink, downlink and total link paths. The relation of rain attenuation and rain intensity is discussed at those links and is compared with the estimation by ITU-R. Characteristics in the wave propagation such as effective path length and specific attenuation based on experimental data are derived and discussed. These experimental results suggest the necessities of detailed study on rain attenuation at local points and of presentation of a method for predicting bit errors, when using effectively Ka-band satellite systems with multispot-beams.続きを見る
