Most of the Synthetic Aperture Radar (SAR) image simulations are focused on the target in the free space and ignores the influence of environment scattering and the scattering from the multipath interactions between the target and background environment. In fact, the interaction for low flying target is strong and can produce undesired multipath signals which can severely affect radar target characteristics...
To theoretically evaluate multipath effect on radar characteristics of low flying target. This letter presents an applicable method in description of multipath coupling between target and ocean surface. It illustrates a composite scale scattering description over physically modelled ocean surface. Then it introduces a facet-based imaging thought in coupling consideration. The method is well suitable...
In this paper, a stable marching-on-in-time (MOT) solution is presented for the analysis of TE transient scattering from two-dimensional (2D) conducting objects utilizing the time-domain electric-field integral equations (TD-EFIE). The TD-EFIE is expressed by the second derivative of the magnetic vector potential which is approximated with a second-order central finite difference. To obtain stable...
An approximation iterative model based on the equivalence principle is described for predicting the bistatic normalized radar cross section of a rough homogeneous layer made up of two rough surfaces.
In this paper, the method of moment (MoM) is used to investigate the characteristics of the GPS (Global Positioning System) signal scattering from the rough sea surface under low grazing incidence, and then on the basis of the results, the GPS signal could be received as the initial field by the improved Discrete Mixed Fourier Transform algorithm (DMFT) method to study the propagation characteristics...
To investigate the electromagnetic (EM) scattering from a PEC target located above a two-layered rough surface, the method of moments (MOM) is introduced in this paper. The incident wave is considered in the vertical polarization. The discrepancies of the bistatic scattering from this composite model and two-layered rough surface only are shown firstly. The influences of the relative permittivity...
