An iterative strategy combining the Kirchhoff approximation (KA) with the hybrid finite element–boundary integral (FE-BI) method is presented to consider electromagnetic scattering from a coated target above a rough sea surface. The multi-hybrid method considers the multiple-scattering interactions between target and underlying surface based on equivalent principle and currents updating scheme. The hybrid FE-BI-KA method, which is an improved and generalized version of a previous KA–Method of Moments (MoM) technique, can deal with an inhomogeneous target. Numerical results are given to evaluate the validity of the multi-hybrid technique, and then the hybrid method is employed to investigate electromagnetic scattering from a plasma-coated airfoil above a rough sea surface, including the effects of several key parameters on stealth performance, such as plasma angular frequency and electron collision frequency.
