| Abstract(in English) | The most serious transmission impairment is caused by the rain attenuation in the radio systems using frequencies above about 10GHz, and it is required to be estimated quantitatively. Practically, it is necessary to know one-minute rain rate distribution for estimating rain attenuation, but rain rate is usually measured only with a longer integration time than one minute. Therefore, it is essential to develop an estimation method of one-minute rain rate distribution from measured n-minute distribution. In Japan, an estimation method of one-minute rain rate distribution from 60-minute rain rate one was proposed by using M distribution, and was confirmed by the comparision with measured data. In this paper, the worldwide applicability of this method is investigated. A good coincidence is observed between estimated and measured one-minute rain rate distributions. Furthermore, the error of this estimation method is shown to be reduced by using meteorological parameters. |
