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
