Abstract

In this paper, we propose a novel method for rain sensing using dual-frequency measurements at 25 and 38 GHz from small-scale Tokyo Tech millimeter-wave network. A realtime algorithm was developed for estimating the rain rate using ITU-R relationships and new coefficients to consider the effects of the rain Drop Size Distribution (DSD). The results show that the proposed algorithm provides the estimation in very good agreement with rain gauge data.
