Effect of a random medium on microwave imaging

The effect of a random medium on the microwave imaging process is experimentally examined by positioning randomly distributed glass beads embedded in thin styrofoam sheets in various densities between the target and the antennas. The main effect of the random medium is a reduction in the signal-to-noise ratio for the tested medium with a small size parameter. If the medium consists of densely distributed particles, it is shown that the image quality is less than that of the sparsely distributed particle medium of the same optical distance. >
