Summary:
Several approximated theoretical formulae among propagation properties, such as rainfall rate, attenuation, depolarization, and so on, have been proposed. These relations are based on the assumption of homogeneous rainfall rate model. In this paper, effects of rainfall rate inhomogeneity on these relations are discussed. In deriving the effect, from empirical knowledge, probability distribution function of rainfall rate is approximated by log-normal one, and spatial correlation properties of rainfall rate, R, and the n-th power of that, Rn, are approximated by exponential-type functions. It is observed that in some relations the effect is not significant from the viewpoint of practical link design.
