The shooting and bouncing ray (SBR) method is effectively implemented on the graphics processing unit (GPU) for scattering problems of electrically large complex target and randomly rough surface composite model. Results obtained using the proposed approach are compared against results generated by commercial software and those obtained with the CPU-based SBR. The good agreement and significant acceleration...
Based on the co-polarized ratio and the co-polarized discrimination ratio of the back scattering coefficient, the inversion of the dielectric constant is discussed in this paper. The value of the co-polarized ratio and the co-polarized discrimination ratio are calculated for minimum effect of surface roughness for the retrieval of the dielectric constant. The ratio of the co-polarized and co-polarized...
The composite scattering characteristics between targets and sea surface in near range illumination conditions are very different from that in the far-field conditions. By using of laboratory-scale wave tank in door to imitate sea environment, we can basically obtain the electromagnetic composite scattering echoes of near-field targets and rough sea surface after being tested. Under the same condition,...
Experimental measurement and theory study on the composite electromagnetic scattering from a combinative object above a one-dimensional sea surface is disscussed in this paper. The experimental part uses hydraulic technology of a shaking plate to simulate the open ocean for 1 to 3 sea state and the measurement was carried out by full-scale method in the simlant pool. The characteristics of electromagnetic...
The characteristics of composite backscattering from a target above a one-dimensional and two-dimensional oceanic surface are investigated with the diffraction of the target fringe taken into account. The backscattering radar cross section (RCS) of the oceanic surface is calculated by the Small Slop Approximation (SSA). The backscattered field of a target is computed based on the equivalent edge currents...
