Research Abstract |
This research is aiming at the estimation of the structure of the heavy rain by examining the multiple scattering analysis for beam waves. For beam width smaller than the scattering mean free length, the multiple scattering effects differ greatly from those for the plane wave incidence. The actual radar echo including the higher scattering generally overestimates the real rain rate. In fact, the comparison of the radar echo between the single scattering the multiple scattering taken into account shows the stronger radar echo by the multiple scattering.
