Model for estimating rain attenuation at frequencies in range 6-30 GHz

摘要

The raindrop size distribution (RSD) for various types of rainfall over Guwahti, India is presented. The observed RSD parameters are compared with those given by other models. By employing the observed RSD, the values of a and b in the relation A=aR/sup b/ for estimating the rain attenuation at frequencies from 6 to 30 GHz are given. The significance of the type of rainfall in controlling attenuation is discussed.
