Study on Composite Electromagnetic Scattering from 1D Weierstrass Fractal Land Surface with Buried Target Using FDTD

1D band-limited weierstrass fractal rough surface is used to simulate the natural rough land surface, the composite electromagnetic scattering from 1D band-limited weierstrass fractal land surface with buried target is studied using FDTD, the angle distribution curves of the composite bistatic scattering coefficient is obtained by numerical calculation, the variation of the composite bistatic scattering coefficient with fractal Dimension, the root-mean-square of height fluctuation, the target size, the slope angle of target, the buried depth of target is calculated, which is analyzed and discussed in detail at the same time, the characteristics of the composite electromagnetic scattering from fractal land surface with buried plate shape target is obtained
