Inference of Raindrop Size Distribution from Rain Attenuation Statistics at 12, 35, and 82 GHz
Summary :
A path-averaged raindrop size distribution is inferred from the equi-probability values of cumulative distribution of rain attenuation measured at 11.5, 34.5, and 81.8 GHz on the same propagation path of 1.3 km in a suburb of Tokyo for three years. By using the size distribution, attenuation coefficients due to rain are obtained in the frequency range from 10 to 300 GHz. The same kind of examination has already been made on the basis of the first one-year data. However, the result obtained this time is slightly stable in comparison with the result for the one-year data in statistical meaning, and is usable for predicting the rain attenuation at frequencies up to about 100 GHz with high accuracy. Moreover, the raindrop size distribution of Laws and Parsons is found to lead to an underestimation of rain attenuation by 30 or 40 percent in dB value at rain rate of 10 to 50 mm/h in the frequency range above about 100 GHz.
