Abstract :
The rain attenuation from 1 to 1000 GHz was calculated by using a Weibull distribution for raindrop-size. The microwave experimental measurement data from 8 to 312.5 GHz were compared with our calculations. Especially, comparison between the submillimeter measurement and calculation at 312.5 GHz (0.96mm) was shown for the various rainfall rates. The empirical relation A = aRb between the specific attenuation A and the rainfall rate R was also found for a rain temperature of -10°C, 0°C and 20°C, and dependences of a and b on frequencies from 1 to 1000 GHz were tabulated.
