Abstract

In quantitative precipitation estimation with point-to-point commercial microwave links, the observed path attenuation of interest can be strongly influenced by wetness on the antenna radomes. Wet antenna attenuation (WAA) can, therefore, cause considerable overestimation of rain rates. In order to better understand WAA, we investigate full-wave electromagnetic reflection and transmission simulations of randomly wetted antenna radomes utilizing a doubly-periodic unit cell model. The physical effects of scattering and absorption of energy by individual water residuals are fully considered in the simulation. We show minimum-maximum ranges of plane-wave transmission and reflection coefficients of the wet radome for different drop densities.
