Numerical analysis of bistatic cross-sections of conducting circular cylinders embedded in continuous random media

To make clear numerically the scattering characteristics for a body embedde d in a random medium, we need to analyze the bistatic cross-section (BCS). The scattering problem can be analyzed as a boundary value problem by using current generator method. The fourth moment of Green's functions in the ra ndom medium, which is necessary for the analysis, is obtained approximately by two-scale method. We analyze numerically the BCS of conducting circular cylinders in continuous random media, which are assumed to fluctuate about the dielectric constant of free space. The numerical results agree well wi th the law of energy conservation. The effects of random media on the BCS a re also clarified numerically.
