Raindrop size distribution extracted from rain attenuation data

Attenuation due to rain plays a significant role in the terrestrial and earthspace communication systems especially at frequencies above 10 GHz. Although models proposed by ITU-R for the prediction of rain attenuation give a good estimation about the signal attenuation caused by rain for temperate r...
