Electromagnetic scattering from a conducting target surrounded by fractal atmospheric turbulence

In this paper, the theory of electromagnetic wave scattering from a conducting target surrounded by fractal atmospheric turbulence is presented. The first and second order moments of the scattering fields are derived by considering the effects of the fractal atmospheric turbulence. The relationships between the mutual coherence function, structure function and fractal dimension are given for plane wave and spherical wave incidence, respectively. The normalized backscattering radar cross section /spl sigma//sub n/ of a perfectly conducting disk is calculated. It is shown that the influence of fractal dimension on /spl sigma//sub n/ is obvious for atmospheric turbulence with a fractal spectrum distribution.
