Study of interference by rain scatter
Abstract
Of the more important aspects of the problem of rain-scatter interference between radio links at frequencies above 10 GHz, some involve electromagnetic phenomena and the interaction between waves and scattering particles, and others the statistical properties of the rain structures and their influence on the interference statistics resulting from the movement of these structures across the antenna beams. The main physical, geometrical and 'system' aspects that play a role in the interference phenomena are briefly reviewed and appraised. The statistical aspects are also considered and the effects of the rain's spatial structure are described. The role of the radiating characteristics of the antennas is also considered. The algorithms proposed are then applied to practical systems and the results discussed. The main areas investigated are the bistatic radar equation, the effect of wave polarization and drop shape, a model for the horizontal structure of rain, a model for the spatial distribution of rain cells, the effect of the real antenna pattern, and the degradation of radio system performance.
