Abstract
A two-dimensional fractional Brown motion (fBm) fractal model is presented, which is suitable for describing the natural rough surface. Using the Kirc hhoff approximation, the expressions of the electromagnetic scattering fiel d and the normalized radar cross section from this fractal surface are obta ined. Numerical results of the normalized radar cross section as a function of the fractal dimension, characteristic length and incidence frequency ar e given. Our fBm model is also compared with classical models of Gaussian a nd exponential correlation.
