Abstract

This paper addresses bistatic scattering of radiowaves by the melting layer of precipitation. The bistatic radar reflectivities are formulated and can be computed at 1-100 GHz by applying the Mie theory for five raindrop-size distributions at rain rates below 12.5 mm/h. Examples computed at 35 GHz are presented. This original bistatic scatter calculation is not only of substantial guidance into bistatic scattering of radiowaves by the real melting layer of precipitation, but also should be appropriate for considering the interference problems including the melting layer effects for engineering purposes
