                         discrimination in Bebedouro region, Pernambuco state, Brasil. In 
                         addition to widely used modulus of complex channels 
                         (amplitude)another two channels, modulus and phase from complex 
                         correlation coeficient between HH and VV complex channels were 
                         also used. The phase of correlation coeficient is a smoothed 
                         version of phase difference information between HH and VV, and was 
                         used in lieu of it. Five classes; corn, soya beans, stubble, bare 
                         soil and {"}caatinga{"} were defined. To assess the discrimination 
                         power of the extracted features confusion matrix of maximum 
                         likelyhood per point classification and Jeffreys-Matusita distance 
                         were calculated for there classes. Results showed that phase 
                         information can greatly improve the classification accuracy and 
                         the modulus of correlation coeficient carries also discrimination
