Attenuation and phase shift of narrowband signals at radar and higher frequencies due to atmospheric layers of hydrometers are usually analyzed by solving the scattering amplitude of one particle numerically and then applying the necessary many-particle statistics. A case is made for an important simplification: use of an analytical solution for the one-particle scattering amplitude that is basically an extension of the well-known low-frequency Rayleigh scattering amplitude with several empirical factors. This opens the road to predictions of 5-90-GHz signal deterioration from lower-frequency radar reflections yielding particle, statistics. Specifically, results for copolar and cross-polar discrimination of signal attenuation and for differential phase shifts are presented and compared, where possible, to known results.< >
