Abstract

Scattering of a TE incident wave from a perfectly conducting one-dimensional composite random rough surface is studied. A composite random surface contains roughness of more than one scale. With the recently developed efficient numerical technique known as the banded-matrix iterative approach, we are able to study large-scale composite roughness with two correlation lengths that are many times different from each other. It is shown that small-scale roughness, with its large rms slope, rather than large-scale roughness, with its small rms slope, can dominate bistatic scattering. It is also shown that backscattering enhancement can also exist in a composite rough surface.
