Description
Summary:In this paper, the finite-difference time-domain (FDTD) method is applied to calculate the radar cross-section (RCS) of anisotropic coated missiles. We present a FDTD algorithm for cylindrical coordinates and derive the necessary extension to the FDTD equations for a general three-dimensional anisotropic scatterer. A new approach is proposed to obtain magnitude and phase information from the FDTD data. Computed results for two selected examples are compared with those obtained by eigenfunction expansion techniques and the moment method (MM) to demonstrate the validity of the new approach with very good agreement. The study of the bistatic radar cross-section for a missile demonstrates that the anisotropic material coating around it can effectively reduce its RCS.
