20GHz Specific Attenuation Calculations using Drop Size Distributions and Drop Shape Measurements from 2D Video Disdrometer Data in Different Rain Climates

摘要

Specific attenuation calculations using drop size and drop shape data are presented for horizontal and vertical polarizations at 20GHz. The data were obtained from several 2-dimensional video disdrometers located around the globe, ranging from mid-latitude to equatorial regions. The results are compared with predictions from the ITU-R recommendation P. 838-3.
