Abstract
The fie d!ff'eenal polarition phase shift KoP has been suggested as a possible estimator of rainfall as wll as rain-had d!SCl"! . mtnator m several recent studies. Here, the complex multivariate Gaussian model, used wide!Y tn commuication theory nd statistical optics, is applied for modeling K0p caused by precipitation. Specifily, the width ofhe mnal phase probability density function is used to estimate ,t,0p (cumulative differential P) fluctuations. !his results in suboptimal but simple expressions, which highlight the dependence of 1/>r,p fluctuations on the magnitude of the HV (horizontal-vertical) cross-correlation coefficient I PHV j. Statistical arguments are rated from the eff' of radar wavelength and Doppler spread. Implications of 4>r,p fluctuations on
