Inquiry into backscattering enhancement phenomenon in random media

Backscattering enhancement phenomenon has attracted considerable attention from radar engineering and remote sensing fields. This paper investigates the phenomenon by analyzing numerically the bistatic radar cross-section (RCS) of a conducting circular cylinder embedded in a continuous random medium. The RCSs of different size cylinders are depicted by changing the fluctuation intensity and thickness of the random medium. As a result, strong backscattering-enhancement and oscillation in the neighborhood of the backward direction are observed for a wavelength-size cylinder embedded in a strong random medium.
