Calculation of the double scattering from lossy dielectric cylinders

A numerical Fresnel Double Scattering (FDS) method is presented in this paper to accurately calculate the bistatic cross sections due to double scattering between two lossy dielectric cylinders in the Fresnel zone of each other. The cylinders have a comparable size to the wavelength for L band frequencies. It is demonstrated that the FDS results reduce to the far field results when the scatterers are sufficiently far apart. The FDS method can be employed to study the double scattering effects between tree branches in microwave forest scattering models.
