Abstract : Or~cl of the main applications of polarimetric radar is to retrieve the cllarac-toristic- ir~forrnation about the liydrometeors in the radar resolution volume. Theirrfor~~iat ion cst raction from polarimetric radar d a t a includes identification of 11~--drorrictcor type. quantitative estimation of precipitating lqdrornetcors. and fore-cast of h?-drometcor evolution. Sonw ,Artificial Intelligent (-41) nlethods. such asfuzz?- logic and Seural Setwork tecliniqucs. are proposed in this rcscarch to addresst lit. issuc~s of 11!-drometeor classification arid quantification. .Fuzz- logic and Seuro-Fuzzy systcrns for the classification of hydronieteortype t~ascd or1 polarimetric radar rncasurernents is developed. The hydrometeorcIassific-ation sj.stcrn is implcmentcd lq- using fuzz- logic 2.nd neural network. wherethc f m q - logic is used to infer hydrometeor t!*pe. and the neural network Iearn-irlg algoritlim is used for automatic adjustment of the parameters of the fuzzys r w in the f u z q logic system.
