Interference-Related Studies of Slant-Path Attenuation and Bistatic-Hydrometeor Scatter

Co-channel interference may be caused by bistatic scattering of electromagnetic waves from hydrometeors. The degradation of a wanted signal on a slant-path link due to interference depends on the signal-to-interference ratio, and thus also on the concurrent attenuation on the wanted path. To investigate these propagation effects, concurrent measurements of bistatic scattering and attenuation have been performed in the 30-GHz band in a realistic scenario. Statistical data are presented for several geometries, to make the results more generally applicable.
