Abstract

It is expatiated that the theory of Radar Cross Section(RCS),disposal of absorbing boundary,addition of incidence wave and transformation of Near-and far-field calculated with Finite Difference Time Domain(FDTD) method.The possible solutions are provided for the improvements to calculative boundary condition of resolving Maxwell equations with FDTD method.The 2D applications are compiled in VC++(6.0) environment and the 2D computing instances are given.Compared with existing results,the application is proved to be valid.
