Abstract

Abstract: Aiming at fast computation of the composite scattering of low-fly target and ocean surface, the improvement of conventional multi-path algorithm is implemented, and a new multi-path algorithm is proposed based on the statistics of mirror facets’ slope. New algorithm takes the modulation from gravity into account in comparison with conventional algorithm. The distribution of mirror facets’ slope is counted from a determined ocean surface, and the multi-path coupling is summed with a weight coefficient, which scatters from mirror facets with different slope. Furthermore, the coupling scattering characteristic is obtained from target and ocean surface. Simulation result indicates that the proposed algorithm could explain how the coupling scattering is affected by the slow change of mirror facets’ slope, and could simulate the G-Brewster effect effectively, which lies a solid foundation for electromagnetic scattering research of the moving target and time-varied ocean surface.
