  • In order to solve the problem of near-field electromagnetic scattering simulation in an interactive scene of missile and target, this paper presents a calculation model based on near-field shooting and bouncing rays (SBR) under the influence of antenna patterns. According to the antenna patterns and the complex geometry between the ship and the sea surface, the electric field intensity received by the surface elements satisfying the far-field conditions of physical optics is given. The scattering fields of all surface elements are determined by the bouncing ray method. Further, the near-field radar cross section of the ship target is measured with vector superposition. The results of the model are in good agreement with the numerical computations in FEKO, which can be used to analyze the near-field scattering characteristics of ships on sea surface.
