This paper uses stochastic bridge processes to model the sea surface multipath propagation channel of Ka-band. That is taking the samples of stochastic bridge processes as the multipath propagation paths of electromagnetic waves. Firstly, through the analysis of the propagation environment and the radio wave propagation characteristics, get the numerical characteristics of the stochastic samples and...
Scatterance of sea surface is a substantial interferon in detecting or identifying objects over the ocean. In consequence, it's vital to derive the scatter echo of sea surface. In this paper, a simulation method that can get fully polarimetric backscatter echo from sea surface is proposed.
This paper presents the characteristics of radio wave scattering from rough sea surfaces in Ka-band. The physical optics method, which is one of the high frequency approximation algorithm, is employed to calculate radar cross section of electromagnetic simulation models of rough sea surfaces with Ship-EDF software. Rough sea surfaces are divided into six levels according to the wind speed over them...
The composite electromagnetic scattering problem from the randomly rough sea surface and the missile-like target is effectively analyzed by the Extended Propagation-Inside-Layer Expansion (EPILE) combined with Forward-Backward method (FBM) scheme. The formulation of the composite scattering is given, the efficiency and accuracy of adoptive algorithm are verified, and different scattering characteristics...
In this paper, Physical Optics (PO) is used to calculate the electromagnetic scattering of electrically large complex target and background. Two dimensional surface is simulated by using spectral method based on PM spectrum. Then, the target and rough surface model are combined together to be a very accurate composite model, after which surface mesh is generated with the information of incidence frequency...
The application of tapered resistive sheet with a incident plane wave to remove edge effects and to reduce the surface length at low-grazing angle in electromagnetic scattering from sea surfaces with finite conductivity has been considered. The use of the forward-backward method that has shown a very fast convergence and sufficiently accurate results, made it computationally effective. The integral...
This paper describes the electromagnetic scattering model with concrete pavement and scattering properties of layered equivalent to a single exponential model of the electromagnetic spectrum engineering rough surface scattering, and then introduced the experimental method to measure the scattering coefficient of cement, the experimental apparatus and measurement system, and then later by the experimental...
Lombardini et al. [1] have demonstrated that the ripples on a sea surface covered by oil films exhibit a damping effect. The damping effect reduce the RMS slope and RMS height of the sea surface, and thus have an influence on the electromagnetic scattering features, as well as the Doppler spectra signature of the backscattered returns from dynamic sea surface. Consequently, electromagnet tic scattering...
