Název v původním jazyce
Investigation of wet antenna attenuation dynamics of cellular microwave links
Popis výsledku v původním jazyce
Use of microwave attenuation for path-integrated rain rate estimates attracted broader attention of scientific community in recent decade with extensive global growth of cellular microwave link (MWL) networks (Messer et al., 2006). Quantitative precipitation estimates from MWLs are, however, often biased by additional attenuation, so called wet antenna attenuation (WAA), caused by microwave scattering on wet radomes of antennas. Although, there have been several studies investigating this phenomenon (e.g. Leijnse et al., 2008) the dynamics of antenna radome wetting and its effect on WAA is still not well understood. This investigation therefore focuses on quantitative and qualitative description of WAA dynamics and presents initial results of dedicatedexperiment based on direct measurements of antenna wetting in our experimental catchment in Prague, Czech Republic.
