Abstract

Electromagnetic scattering from raindrops at 94- and 140-GHz frequencies is investigated. The differences in the scattering properties of spherical and oblate spheroidal model raindrops are illustrated for side and vertical incidence cases. Various backscattering and propagation parameters are evaluated using the Marshall-Palmer, Joss thunderstorm, and Joss drizzle drop size distributions. The Doppler spectrum at vertical incidence is substantially affected by the model raindrop shape. The radar reflectivity and the specific attenuation are not significantly affected
