Abstract

The effects of spatial distribution of the scattering elements on microwave emission from random media have been investigated using an experimental model composed of long, thin vertical dielectric cylinders on a reflecting screen. The measurements have been carried out at 10 GHz, H, V and 45° polarizations and different incidence angles between 10° and 50°. Uniform and cluster distributions with different volume fractions have been studied. Some emission enhancement has been detected when the cylinders are distributed in clusters
