Comparison of the Coherent Attenuaton Predicted by Single and Multiple Scattering Theories for the Case of Several Types of Hydrometeors.

Abstract

A systematic computation has been completed in order to compare the difference in the coherent attenuation predicted using multiple and single scattering theories. This is the first study in the literature to examine quantitative results based on two different scatterng theories. Therefore one is able to tell the approximate range, in both frequency and concentration regimes, where single scattering theory can be applied for different types of hydrometeors. However, the computations give exact figures up to the four decimal place and reveal that, in most cases, if interactions among scatterers are not considered, the coherent attenuation can either be over- or under-estimated. This is a serious problem in communications between distant stations. Keywords: Coherent attenuation; Scattering theories; Hydrometeors; Communications; Mie scattering.
