Sadeghzadeh, R. A., Glover, Ian and McEwan, N. J. (1993) Analytical calculation of bistatic radar cross-sections for rain scatter problems. International Journal of Satellite Communications, 11 (3). pp. 163-168. ISSN 0737-2884

A formula is derived for the effective bistatic radar cross-section of a rain cell with Gaussian reflectivity profile assuming antennas with Gaussian radiation patterns. The size and location of the rain cell are arbitrary, as is the bistatic scattering geometry. The expression is analytical, avoiding the need for numerical integration, and general, allowing treatment of cases with only partial beam intersection. Using a recently proposed model, sidelobe contributions and multiple cells embedded within widespread rain debris can be incorporated.
