Modeling and Electromagnetic Scattering of Ground and Near Sea in Adjacent Region with Fractal Borderline
Abstract— A novel composite rough surface model is presented for describing ground and near sea in
adjacent region. Monte Carlo method is used to generate composite rough surface. Gauss spectral function is
used to simulate actual ground surface, and JONSWAP spectral function which is combined with shallow
coefficient is used to simulate actual near sea surface. Weighted inverse tangent function is presented to
connect two regions and smooth the borderline. One dimensional band-limited Weierstrass fractal function is
introduced to simulate the actual borderline between ground and near sea in adjacent region. The geometrical
models of composite rough surface with linear borderline and fractal borderline are given. By comparing of
the contour maps, the geometrical model of composite rough surface with fractal borderline is closer to real
environment of ground and near sea in adjacent region than the one with linear ，borderline. The curves of
bistatic scattering coefficient of ground, near sea and composite rough surfaces with linear and fractal
borderline are compared. This paper presents a novel way to simulate the environment of ground and near sea
in adjacent region. Simulation results can use for reference in the fields of remote sensing, detection and
inversion of electromagnetic environment.
