| Abstract: | A useful method for calculating RCS of complex objects is given. First, it models the armored car with triangular element by using 3D Studio Max. Radar scattering character is calculated with Ludwig's integration and the physics theory of diffraction. The method is effective validated by calculating RCS of the cuboids. The radar cross section of armored cars and tanks is presented, which is important in studying scattering characters of the targets. |

| Keywords: | radar cross section(RCS) triangular object model electromagnetic calculation |
