摘要：
In order to numerically simulate bistatic scattering from a fractal rough surface at low grazing angle (LGA) incidence, a hybrid approach of the forward-backward method (FBM) with spectral accelerate algorithm (SAA) to solve the magnetic field integral equation is developed. Numerical bistatic scatterings from one-dimensional perfectly conducting fractal rough surface with and without a regular object presence are accomplished. Accuracy and efficiency of FBM/SAA are discussed. Numerical simulations demonstrate functional dependence of bistatic scattering upon fractal geometry, especially at LGA. The linear relationship between the envelope slope of bistatic scattering pattern and fractal dimension is discussed.
