2-Year Results of Hydrometeor Attenuation Research at 93 GHz on an 850 m Terrestrial Path

The results of 2 years of experimental research of attenuation due to hydrometeors at 94 GHz with V polarization on an 850 m path are presented. Both the cumulative distributions of attenuation due to all the hydrometeors together and the cumulative distributions of attenuation due to the individual hydrometeors are given. The influence of the individual hydrometeors on attenuation is assessed. The obtained cumulative distribution of rain attenuation for the 2-year period of observation is compared with the one calculated for the average year in accordance with relevant ITU-R recommendations.
