  • RCS of engine duct was calculated and analyzed using SBR method.EM scattering characteristics of the pipe with arbitrary section and shape were studied by the methods of shooting and bouncing rays,field intensity track and aperture integral.In the ways of vertical polarization and horizontal polarization,real measurement at the frequency of X wave band was done in the anechoic chamber.The calculation was compared with the experimental result for a real engine duct.It proves that this method is very effective.Compared with other methods,its physical conception is clear,mathematical models can be set up more easily and it also meets practical needs in engineering.
