    Abstract
  • The general formulas of the scattering field when the parallel and vertical polarization plane wave incident on the objects are given.The method of determining the strong scattering source of complex objects,and the effective method of selecting region coated with radar absorbing material(RAM) are presented.At the same time,the electromagnetic field scattered from three dimension complex objects partially coated with RAM is analyzed.At last,the calculated results are given,and the validity was tested.The method improves the calculation accuracy of complex RCS,and is fit for the engineering application.
