Tropical raindrop size distribution (RSD): prediction and modelling its effects on microwave propagation

摘要

The paper present the observed raindrop size distribution (RSD) during various types of rainfall viz.. thunderstorms, drizzle and showers and discusses the power law A=aR/sup b/, by employing the observed RSD over Guwahati, one of the most rain affected regions of the world. The values for the coefficients a, b are computed for each type of observed RSD. Finally the specific attenuation (A) values, predicted with the calculated values of a, b are assessed with those experimentally received over an LOS link operating at 11 GHz. This link is an intra-city network 3.2 km long.
