Based on In-Homogeneous Dielectric SBR Method for Research on Electromagnetic Scattering Characteristics of Coated Targets

In this paper, the flow field of hypersonic vehicle is combined with the propagation of electromagnetic waves in the plasma sheath, and the dielectric metal composite target is modeled and simulated. Based on the Shooting and Bouncing Rays (SBR) method, the ray path is traced and the scattering field of the outgoing surface is solved by integrating. The electromagnetic scattering characteristics of dielectric metal composite targets under different incident conditions and flight conditions are analyzed. The results show that different EM wave incidence modes and the electron density changes, which caused by different ionization degrees of air on the surface of the aircraft and different flight heights, will affect the peak value of the Radar Cross Section (RCS) of the target. The relevant research of electromagnetic scattering characteristics in this paper can provide theoretical reference for the imaging, navigation and communication of aircraft targets.
