Abstract : Within the scope of rain measurements with a bistatic dual-polarization radar, the influence of multiple scattering effects is discussed. The determination of multiple scattering intensities (up to the sixth order) for frequencies of 33 and 94 GHz in dependence on rainfall rate, single scattering albedo, volume scattering coefficient, number of ground reflections, antenna beam widths, and dimension of the rain volume was done by the aid of an efficient Monte Carlo algorithm. The results show that multiple scattering cannot be neglected interpreting the scattered electromagnetic field on the basis of the normal radar equation. The portion to total scattering can become more than 5% for shorter microwaves and stronger rain rates (say 50 mm/h).
